Tomsula details views on 49ers' analytics department

SANTA CLARA – Coach Jim Tomsula categorized himself Friday as a coach who studies analytics and “absolutes” when it comes to making game-management decisions.

Team president Paraag Marathe, who had been deeply involved in studying football analytics since coming to the 49ers 15 years ago, stepped away from the day-to-day football analytics in recent years, Tomsula said.

“Early on, years ago he was really involved in it and we did some things,” Tomsula said. “I was able to be in meetings that he was a part of . . the analytics. The factual, time and stuff like that, which I thought was really good and interesting.”

Marathe’s title with the 49ers will change after Super Bowl 50 at Levi’s Stadium on Feb. 7, sources told CSNBayArea.com on Thursday night. He will still be in charge of managing the salary cap and being the club’s top contract negotiator.

According to sources, Marathe will concentrate more of his attention on the 49ers’ outside business interests. The focus of his duties was described in the 49ers’ 2015 media guide, which was released in July.

“He also has a significant position in the club’s New Ventures effort, where the team looks for investment opportunities in and out of sports to expand the 49ers brand,” the media guide states.

When asked about Marathe’s new role with the team, Tomsula said, “No, I don’t have any knowledge, don’t have any comment, don’t have anything.”

Tomsula said he now works closely with Brian Hampton, the team’s director of football administration and analytics.

“So much of it to me is gut and feel and those things,” Tomsula said. “Obviously, the absolutes in math of where you can save 20 seconds here or 30 seconds here, obviously we pay attention to.”

Tomsula confirmed that his decisions on Nov. 22 to twice punt late in the game with the 49ers trailing by 16 points against the Seattle Seahawks were supported by the team’s statistical research.

“Statistical information and the analytics right there,” Tomsula said. “Yes, it’s backed up.

“And what every decision we make, that’s information I ask for. (Tight ends coach) Tony (Sparano) is involved with me there as we study those. And Hampton comes down. We go through that every week.”

Internet reports suggested that Tomsula did not show up at the team’s practice facility on Wednesday because of a disagreement with Marathe.

“Absolutely false,” Tomsula said. “Untrue.”

Tomsula said he arrived at work between 4 and 4:30am on Wednesday and had to leave the facility. Tomsula did not state the reason for leaving, but all indications are that it was not work-related. He postponed his scheduled Wednesday morning press conference to Thursday morning.

Tomsula said he was back in time for the 11-on-11 work during practice on Wednesday as the 49ers began preparations to face the Chicago Bears.

Nick Mullens earns more respect from Kyle Shanahan, remains 49ers' QB

Nick Mullens earns more respect from Kyle Shanahan, remains 49ers' QB

SANTA CLARA -- 49ers coach Kyle Shanahan came out of Monday’s game believing Nick Mullens took a step forward in his development, so he'll remain the team's starting quarterback.

Mullens' stat line wasn't nearly as impressive as in his Week 9 debut against the Raiders, but his performance in the 49ers’ 27-23 loss to the New York Giants went beyond the stat line.

“Nick Mullens is our starter until I say different,” Shanahan said Tuesday.

Mullens completed 27 of 39 passes for 250 yards and one touchdown with two interceptions for a 73.7 passer rating. His TD was an 11-yard pass to Matt Breida, who was the last option in Mullens’ progression.

“What I liked about Nick is that he never seemed rattled throughout the whole game, continued playing,” Shanahan said. “He was great after the game, and he was great just watching the film with him.”

Shanahan gave Mullens an earful Monday night because of what he believed at the time was an lost opportunity for a big play against the Giants. Shanahan ended up with even more respect for Mullens after taking a closer look at the play Tuesday.

“There was one that I thought live he should’ve gotten to a deeper guy from my view on the sidelines,” Shanahan said. “I got on him for it because I wanted a bigger pass. I thought he was there, and it was open.

“He sits there, listens and takes it. When I watched the film, if he would've gone for what I wanted, I think it would've been a sack. And it would've been second-and-15. So that stuff, I like.”

Through two games, Mullens has yet to be sacked while attempting 61 passes. Jimmy Garoppolo was sacked 13 times in 89 pass attempts this season, and C.J. Beathard was dropped 18 times in 169 pass attempts.

“He’s got a feel for that in the pocket,” Shanahan said of Mullens. “I always want to be aggressive and go down the field and get bigger plays, but not at the expense of risking a sack. I think he’s done a good job with that.”

49ers snap count: Ahkello Witherspoon actually played well, analytics show


49ers snap count: Ahkello Witherspoon actually played well, analytics show

Ahkello Witherspoon was involved in a couple of notable plays in the 49ers’ 27-23 loss to the New York Giants on Monday night. But the cornerback was deemed to have an exceptionally good game in coverage, according to Pro Football Focus.

Witherspoon was targeted five times, surrendering only one catch for 11 yards, according to PFF. Moreover, Giants wide receiver Odell Beckham didn't catch any of the three passes thrown his way while Witherspoon was in coverage against him.

Witherspoon was called for a debatable 16-yard pass-interference penalty on a play in which Beckham didn't even look back for the ball before Eli Manning’s pass arrived. But Witherspoon didn't look back, either. The play was significant, as it came on the Giants' game-winning drive.

Afterward, Witherspoon was asked if he disagreed with the call.

"I did, but I also disagree with me not turning my head because I could’ve had an opportunity for an interception on that play,” he said.

Witherspoon was in a trail position on Beckham’s 20-yard touchdown catch in the third quarter. Witherspoon was supposed to have safety help over the top on the play. PFF didn't assign blame to Witherspoon, who let his frustration show after the play.

Here are other notable metrics out of Monday’s game from PFF:

-- Cornerback Richard Sherman was targeted four times and gave up just two catches for 10 yards. He stopped running back Saquon Barkley for a 3-yard loss after a pass completion.

-- The 49ers missed just two tackles all game.

-- Running back Matt Breida graded out as the 49ers’ top offensive player. He gained 101 rushing yards, 65 of which came after contact.

-- Left guard Laken Tomlinson did not allow a QB pressure. Right guard Mike Person allowed only one hurry in 43 pass-blocking snaps.

-- Quarterback Nick Mullens completed just 3 of 9 passes for 12 yards while under pressure. When under duress, he threw an interception and had a passer rating of 3.2.

-- Giants quarterback Eli Manning was under pressure on just seven of his 32 dropbacks.

-- Defensive end Arik Armstead was the 49ers’ top-graded defender. He had two pressures and two run stops while playing 31 snaps.

-- No 49ers player had more than two quarterback pressures. Armstead, Cassius Marsh and DeForest Buckner had two pressures apiece.

-- Linebacker Fred Warner had three run stops and two pass breakups. While in coverage, Warner allowed five receptions on eight targets for 37 yards.
