Terron Armstead...is he gone?

The problem I have always had with he and Peat (more so with Peat) is that it seems like they collectively miss an average of 3-5 games every season. When that happens the OL then becomes musical chairs as everyone gets shuffled around. If Armstead is ranked as a 10 when healthy, but oft-injured...I would rather have a 7-8 who stays healthy.
