Greg Cosell, a senior producer at NFL Films, believes 49ers quarterback Jimmy Garoppolo “has a chance to be a top-level quarterback.” But there remains room for improvement from the player the 49ers awarded a franchise-record contract in the offseason.

Garoppolo has a quick release and can throw at a number of different arm angles to avoid oncoming pass-rushers. And while his accuracy underneath was unquestioned during his 5-0 run as the 49ers’ starter last season, most of the time, his deep throws did not reach the target.

Garoppolo completed just 4 of 16 attempts to targets 20 yards or more down the field last season for 134 yards and no touchdowns with no interceptions, according to Pro Football Focus.

During the offseason program, Garoppolo appeared to struggle on his deep throws, too. Cosell, a guest on the 49ers Insider Podcast, spoke about Garoppolo’s mechanics.

“Because he has very quick feet, I think people just assume he has great feet all the time when he delivers the ball,” Cosell said. “There’s a difference between having quick, athletic feet and having really good quarterback feet. And I think he needs to work on the quarterback feet part.

“I think guys who have that kind of snap delivery, sometimes they don’t step exactly to their throw and they throw a little bit off-balance, and that could really impact your accuracy to a significant degree. So my guess is those are the kinds of things they’ve worked on. Those are tweaks. I don’t think it will prevent him from being a really good player.”

 

Garoppolo appeared in six games with five starts last season after the 49ers acquired him for a second-round draft pick in a trade with the New England Patriots. Garoppolo completed 120 of 178 pass attempts (67.4 percent) for 1,580 yards and seven touchdowns with five interceptions.

Cosell said it is important for all quarterbacks to use consistent mechanics when making throws from a clean pocket.

“Think of a major league pitcher,” Cosell said. “They theoretically should throw the ball the same way every time. So should a quarterback unless the defense dictates otherwise. If the defense doesn’t dictate otherwise, the throws should look the same.”
