Zach Ertz's statistical growth is pretty easy to measure.
In eight games this season, Ertz has 43 catches for 528 yards and six touchdowns. He leads the Eagles in every category and that's even after missing the Denver game with a hamstring injury before the bye. (He'll likely be back this week.)
It's a little harder to measure Ertz's growth as a blocker. But there has been a ton of growth since his arrival in Philadelphia in 2013. He has gone from being a liability as a blocker as a rookie to a decent blocker in a few years.
How rare are truly complete tight ends?
"Those guys are hard to find," Eagles tight ends coach Justin Peelle said last week. "Really, you gotta understand that tight ends, in general, are always going to give up size and strength, just because most of them are 250, 260, where most of the defensive ends they're blocking are upwards of 300 pounds. Then it comes down to technique and your strength and things like that. Those guys are really hard to find."
Coming into the NFL, it was pretty clear Ertz had a ton of natural ability as a pass-catcher and that ability has shown itself. But as a blocker, things didn't come naturally.
It has taken years of work and emphasis from coaches and veteran Brent Celek, who is regarded as a really good blocking tight end.
"That's always been something that's not his strength," Peele said. "He takes pride in it, he wants to be better. He doesn't want it to be a weakness but it was not a natural thing for him. We worked a lot on his technique, his hands, his understanding of the game. You have to consistently work on it and to his credit, he's embraced it and hasn't shied away from."
The Eagles have allowed 54 quarterback hits this season, which places them 12th in the NFL. On all but one of them, Carson Wentz was the recipient. And Wentz takes some more hits out of the pocket.
Wentz has been hit more than the Eagles have probably been comfortable with and he's been sacked 23 times. Sure, the offensive line gave up some of them, but Wentz deserves some blame too. There's a fine line between trying to gain extra yards and taking an unnecessary hit.
Where's that line?
"No. 1 is, protect yourself, whether it's sliding, going down, getting out of bounds. That's the first thing," head coach Doug Pederson said. "I've said this before that unless it's the game-winner in the Super Bowl, protect yourself. That's the line."
For the most part, Wentz has gotten better at protecting himself this season. There are still times, though, where he'll avoid pressure and leave his coaches and fans holding their breath.
The conversation isn't going anywhere.
"It's part of it. It's always a process," Wentz said. "We talk about it, shoot, it seems like every week. Just about where you can improve in every facet of the game and that comes up as well."
North of the border
Every once in a while, I take a look through CFL rosters just to see if there are some names I recognize. I'm aware this is unusual.
But during my perusing, I happened to see plenty of former Eagles on CFL rosters. Some of these names you probably haven't heard for a while.
Eskimos: Edmonton features two notable former Eagles. Yes, Aaron Grymes and Phillip Hunt are teammates. Grymes was a defensive back who was with the Eagles for the last two preseasons and came pretty close to making the team. After getting cut this year, he went back to the CFL, where he has been an All-Star. And remember Hunt? He was with the Eagles from 2011-13. He played 22 of his 24 career NFL games with the Eagles
Blue Bombers: Chris Givens has landed with Winnipeg this season. He was Howie Roseman's cheap speed option before the 2016 season but was cut in August. He didn't have much of a role with the Blue Bombers this season, returning nine kicks for 184 yards.
Tiger Cats: QB Everett Golson was never actually on the Eagles' roster but he did come in for a tryout with the Birds in 2016. The Notre Dame QB is a backup for Hamilton. He completed all four of his passes in 2017 for 25 yards.
Alouettes: Montreal has a couple former Eagles receivers in T.J. Graham and B.J. Cunningham. Graham was with the Eagles in the 2016 offseason and Cunningham bounced around with the Eagles from 2012-14, playing in two games in 2013. Cunningham has actually become a really good CFL receiver. This season, he had 69 catches for 1,128 yards (8th in the CFL) and four touchdowns.
Argonauts: Toronto is officially the old Eagles landing spot. Mitchell White, who was with the Eagles this offseason, is back in the CFL. He's there with former Eagles quarterback McLeod Bethel-Thompson and linebacker Akeem Jordan. Remember Jordan? He spent 2007-12 with the Eagles and played 82 games with 34 starts. Not bad for an undrafted rookie. Bethel-Thompson was actually the first QB Pederson brought in as head coach; he would later bring in one a little better.
There are just four teams left in the CFL playoffs — the Roughriders play the Argonauts, while the Eskimos play the Stampeders. Winners go to the Grey Cup.
