A couple of things:
First, the OLine didn't look that bad. I started breaking down and scoring the reps from this film, but gave up when it became too difficult to figure out who the players were because of poor video quality, shots blocked by other spectators, etc. At the point where I stopped, I'd scored 3 wins for the DLine, 2 for the OLine, and 1 rep that was a draw. Yes, Coleman got beat in one rep, and Charles Mosley got beat in another, but those were just two reps out of several. Taken as a whole, it was not overwhelmingly tilted in favor of either side.
Second, in the clips above, we saw one or two reps per player. Yesterday evening, Coach Jones mentioned that some of these players have been through 300-400 reps so far in fall camp (he was talking about WRs at the time, but you can run a Line rep about as quickly as a QB-WR pass rep, so they should be comparable). Point is, we shouldn't think we know much at all about how these players are doing based off the grand total of 5-10 reps we've seen each of them run. It's a drop in the bucket to what the coaches are seeing.
I'm following the OLine's development this fall as closely as anyone else here in VN, but we shouldn't make the mistake of thinking that we can see enough to determine how well or poorly things are going. We're just gonna have to depend on the coaches' assessments for that...and see how it works out when we actually start playing games.
One thing's for sure: thanks to practicing against such a talented DLine, our OLine--Coleman, Jashon, Jack, Mack, Brett, Kerby, and all the rest--are going to be far better in September than they would've been otherwise. That's the primary reason I have hope for something good in 2015.
Go Vols!
