2013 had a lot of different issues though. We didn't aquire Monroe until mid-season and K.O suffered a season ending injury. If we had a line of Monroe-K.O-Gradowski/Shiply(Yeah they both suck)-Yanda-Oher, then I don't think the line would've been nearly as bad. Obviously the OL we had to begin with was horrible but I think we overestimated Mckinney and Oher after their spectacular playoff performances.
We literally had an OL with only two players worth starting and one of them ending up missing the entire season.
A couple things-
Monroe was just before week 4 and started week 5 on. Kelechi Osemele started the first seven games. We got to see three games of Monreo-KO-Gradkowski-Yanda-Oher.
Now, how much of Osemele's poor play in 2013 (he really wasn't that great) can be attributed to the injury? I'm not sure, honestly. He was new to LG, so maybe that had something to do with it? I didn't think the injury started creeping up for him until week four-ish, but don't quote me on that.
Yanda had arguably the worst season of his career, especially in recent memory. Was this due to being sandwiched between Gradkowski and Oher? I'm not sure. I can't remember if he had injuries or not in 2013 after the season. I know he played in all 16 games.
I just completely worry about how bad Skura is. The last time we saw Hurst play tackle in live games, he gave PFF their two worst graded games ever.
