We have so many holes that there is a case to be made at a lot of positions. WR, RB, DE and obviously QB. But I really wouldn't mind Kalil at all. I think it would give us the best offensive line in football right away. Giving a quarterback that extra time to throw is just huge, and being able to run to either side changes everything. Pashos KILLED us this year.
I'd still prefer Blackmon, but I like Kalil over a second CB.
