1) A'Shawn Robinson is 6'-4" & 330 lbs and only 25 years of age. We've needed a stalwart in the middle capable of stuffing the run for too long now. Additionally his presence should cut down on the number of snaps Donald is double teamed & sometimes even triple teamed.
2) On the other side of the ball, I look for Havenstein to regain his form. He played hurt last year and was not effective - ultimately giving way to Evans. When healthy, big Rob can be a devastating run blocker particularly in tandem with the Higster. The flip side is that he can be vulnerable to speed rushers on passing downs. That said, if our running game is thriving, we won't have to throw the ball as much.
3) Cam Akers - one never knows for sure how well a college player's skills will transition to the NFL. However, I really like his chances given his ability to gain yards after contact. If he flourishes early, he'll be ridden often. I'm sure Goff has his fingers crossed ..
