OL size has been interesting. I remember for years pointing out to Joey that UW would always have like 6’3-4 290 OTs and even schools like Cal and Arizona would have 6’7 320 guys and wail on us and when we finally ended up looking like that our lines were better.
It has seemed like that has mattered less in recent years. Fautanu and Rosengarten weren’t huge. A lot of the OTs you see go high in the draft now aren’t huge.
Does size matter anymore?
I believe size gives you a better chance of having the actual most important thing. Strength. Just a theory so if you come at me with some logic I'm all ears.
Aaron Donald is relatively small but hes insanely strong. Vita Vea also a top end DL because he's a strong guy but he needs more size to get that strong.
Troy Fantaloowoa isn't massive but he's pretty big and you can tell he's very strong.
So if you are recruiting lineman and you need to project 2 years into the future if they will get to the necessary floor for strength then it's alot more probable the stout 6'6" can get there than your Brailsfords or Harris'.
So size is just an odds play as much as anything IMO.
