Without better line play, it won't matter who is back there. These guys have to do a better job of run blocking. Maybe a bigger dose of that will help. I hope McCarthy dials in a very liberal amount of runs these next 4-6 weeks, to get his OL used to pounding the crap out of our opponents.
I wouldn't mind Grant coming in if they deemed it necessary, but I think they may just try to stick with what they have got. As Pack93z said, who do we cut? I'm not seeing it. I would imagine McCarthy will place more emphasis on the run all the way through the bye and into DET. That ought to get his guys on the right track. In the process, Starks should see some reps, and who knows? Maybe White too.
