Tonga seems to be blowing hard after 1 play, and the others seem that way too. I hope Tonga can get some serious conditioning in between the end of the season and BYU's pro-day, so he can get drafted on day 1 and make some money. I fear that he will end up being a project type player though, just simply because his conditioning has been so suspect.
It seems our DL has been going the opposite direction of our OL. I remember during the Bronco years that our OL seemed to be very rotund with a lot of dunlap guts. Since Sitake has been here, our OL seems to have gotten pretty trim (still huge guys, but seem a lot less fat), and our DL has gone the opposite way. As to why the DL seems to struggle, I think the constant dropping of 8 into coverage is certainly making them look worse than they really are.
