Gettleman was the master of getting 1 thing right for every 4 things he got wrong. For instance, he got us Thomas, but he never filled in the other 4 OL positions.
In general, I would play the young guys to see what we got. Keep going with Banks, Hawkins, but also we need to see more of Hyatt and Robinson (Slayton and Campbell aren't the future here), plus keep McKethan at RG, let's see what we have with Ezeudu at LG (Bredeson and Glowinski aren't much better, and aren't the future), put Eric Gray into the rotation at RB as well. Also more Riley at DT, and rotate Basham more into the mix on the DL as well.
Barkley, Bredeson, Glowinski, Leonard Williams, Slayton, Campbell, etc aren't this team's future.
