Iupati and Veldheer certainly played like old fogies, when healthy. Health is also an issue.
We haven't seen Boehm at center yet because he hasn't been good enough to beat out Shipley. Let that sink in, because it ain't good.
Boone might be alright were he the weak link in the line, not playing on a line of weak links.
No one expects us to go sign five all-pro OL. I'm just commenting on how bad we are at the position, currently. We have gaping holes there, at QB, and at RB. Our offense is in absolute shambles. Like, "I doubt we'll achieve even the barest competence to take pressure off our D" kind of shambles. IMO, it will probably take more than one offseason to fix it all.
