OL depth is a problem that both the Diaco regime, and the Pasqualoni regime talked about publicly - since their respective proverbial day 1's on the job. Diaco's situation is actually better than Pasqualoni's was with regard to OL depth. We didn't recruit enough OL's, in Edsall's later years, and of the number we did recruit, we didn't keep enough OL's in the program. There is always attrition with players. This isn't debateable friend.
To try to keep this on track though, QB play - OL play, they go together like peanut butter and jelly, ice cold milk and an oreo cookie. Blocking calls, adjustments at the line of scrimmage, identifying defenses and communication - it happens right up the gut with the C - QB. We've got a senior center starting on the OL. THe last time we had a senior center starting on the OL was 2011. That was the last time we made it to the final game of the season, and had a legit chance at the post season. Coincidence? Maybe - maybe not.
