Run blocking is where I would expect the improvement.
Somewhat, not markedly. Again, Cook was underrated as a run blocker. No TEs, including Bennett, go out and pancake guys. Cook was consistent in getting on his man and shielding him away from the play.
When Cook came in, I was surprised when the Captain reported that PFF graded Cook as something like the 11th. best run blocker in 2015 . So, I started watching some of that in game replays. 11th.-level looks about right, maybe better as the trend has continued toward oversized WRs at the position.
Even if Bennett is the #1 run blocking TE in the league, when you get down to it the difference between 1 and 11 is not that great. Maybe 1 better block per game.
Upgrade with these 2 new guys? Marginal perhaps, but with Bennett on the field most of the time you've lost a more potent downfield threat in Cook.
Now, if one expects McCarthy to suddenly go heavy with Bennett in-line at TE and Kendricks out of the slot for stretch- the-seam, which means benching Cobb in the staple 3 wide/single back, that's unrealistic. We'll probably see it, but it's not transformational in any way. If Kendricks proves up, we might see him in the slot in 4-wide with Bennett actually on the bench! Of course either of these scenarios leaves many fans' new favorite toy, Allison, not seeing the field at all.
