What was Tevin great at? He wasn't a great runner, speed or power. He wasn't a great passer. He wasn't great under pressure, even as a senior. Hell I don't even think he was that great at making reads. Not bad, but certainly no option wizard. We don't have the luxury of talent surrounding the QB to allow for us to have a game manager at QB and that's what he was, which is fine for a back up, but not what we need in a starter.
His senior year we produced 1.4 ppd against VT and he made the critical mistake of trying to force a pass that led to the INT that basically sealed that game. People forget that following that VT had first and goal from the 1, but the defense rebuffed Logan Thomas 3 straight times forcing a FG. Yet it didn't mean anything because we got 0 points in OT allowing a FG to win rather than tie. The inefficiency of the offense was bad enough, but the INT is simply a play that a senior starting QB with as much experience as he had cannot make.
Against Miami - 36 points is fine, but we had a 17 point lead at one point, and a 14 point with the ball at one point. In this situation a senior QB needs to be able to put the game away with either long drives taking lots of time of the clock, not just a bit over 3 minutes, or preferably points. But we didn't. We punted 3 straight times, with only one semi-successful drive of just under 5 minutes. Then in OT on 4th and 1 he checks into a play, but doesn't inform the team. He gets stuffed and once again we get nothing in OT. Did the defense also play poorly? Yes. Did our offense have the chance to put the game away and not do so? Yes. Again, that mistake in OT is simply something a senior QB cannot do.
MTSU - 28 points against MTSU is simply bad.
BYU - 9 possession and 3 offensive points.
FSU - 1.5 ppd
UGA - 8 possessions and 3 points. before getting pulled.
USC - The team as a whole was under 2 ppd, and the scoring drives were a Lee drive, a 1 yard Washington drive set up by a big punt return, and a washington drive.
Simply looking at ppd doesn't tell the story of 2012. Does our defense deserve blame? Absolutely. Did Washington, as senior, play to a starter level. No. He didn't.
Okay. I get where you're coming from. Fwiw, I agree that just looking at ppd does not tell the story of 2012, especially if you only look at select games where we did not do as well. It should be noted that ppd stats, like the more familiar Scoring Offense (PPG) stats are more meaningful with more games because the quality of the competition begins to even out. Also, in 2012, we began introducing a lot more shotgun/pistol sets. We also began using Vad more. So, yeah, the story of 2012 is difficult to tell with stats.
Someone in a recent thread warned about the temptation for people to make stuff up when to support their case. I don't think you did that, but you did assert something misleading about the 2012 UGA when you said, "8 possessions and 3 points. before getting pulled." That was stated rhetorically well, but it's not true. Let's look at what happened in that game (according to ESPN data):
Drive 1: Tevin leads the team 84 yards in 9 plays to the UGA 20. Godhigh loses the fumble on the next play.
Drive 2: Tevin leads the team 54 yards in 12 plays to the UGA 21. FG.
Drive 3: Vad leads the team 26 yards in 10 plays; turnover on downs (UGA 42)
Drive 4: Vad leads the team 29 yads in 5 plays; interception (pass thrown from GT 47)
Drive 5: Tevin leads the team 56 yards in 12 plays to the UGA 19. Missed FG.
Halftime Score 28-3.
Drive 6: Tevin 3 plays -11 yds to GT 14. (3rd and 5, in pistol and ball is snapped over Tevin's head and Tevin goes back and falls on it 16 yds behind los)
Drive 7: Tevin 3 plays 5 yds to GT 20.
Drive 8: Tevin leads the team 51 yards in 9 plays to UGA 25, turnover on downs next play (score was 42-3)
Drive 9: Vad leads the team 48 yards in 7 plays, turnover on downs
Drive 10: Vad leads the team 71 yards in 6 plays, TD, 42-10
Drive 11: Vad leads the team 14 yards in 11 plays (there were 15 yards of penalty), turnover on downs.
FWIW, I look at the story of this game with respect to QB play differently from you.
I guess, someone else might look at JN vs Iowa at the end of 2009, and the games against KS and Clemson and WF as a Senior in 2010 and bring up his decision leading to the interception vs VPI that same year and conclude that he was not good enough for a GT starter. People can look at the same data and draw different conclusions, depending on what aspects they bias, especially when you look at particular games.
