After it took Compton and Fisher injuries to get Lavonte David on the field, I take any claim that Bo made all the correct personnel decisions with a mountain of salt.
That being said, had Carne's been better than Martinez, it stands to reason he would have made a name for himself somewhere, what with all his "it" factor.
This is possible but it takes a lot of assumptions to get there. David was brand new on campus and trying to catch two guys who'd been here for two years. And Compton is apparently quite a bit better than many give him credit for considering he started five games and was one of the Redskins leading tacklers last year. Obviously the injuries got him on the field a little faster but we don't know if that was one game faster, five games faster or what would have happened if he had to win the job.
Should have been a day 1 starter, regardless. There was no "trying to catch" anyone. He was head and shoulders the best LB on the roster the day he walked on campus. The fact he was behind them at all tells me everything I need to know. Zero assumption.
But he didn't play within Bo's scheme! That's super-important!
He broke a bunch of records in Bo's scheme. So there's that.
Didn't the two greatest defensive players in the Pelini Era arguably break scheme more than anyone? Suh didn't sit around in his two-gap responsibility and let the play come to him, he routinely beat his man (or a double- or triple-team) and attacked the ball. The one glaring time I can remember Suh not breaking scheme was when we had Tyrod Taylor bottled up but didn't aggressively attack him and he made that long pass play when the WR got behind everybody. Had Suh attacked like he did against Colt McCoy in the Big XII Championship Game, we would have won that game. Oddly, Bo may have "learned his lesson" from that play and allowed Suh free rein to attack at will - and he was one second too good at it against McCoy. So it goes.
David, it seems, was a free agent much of the time. He played within scheme when it suited him, but made so many tackles, so differently than any other linebacker in the Pelini Era, that it's difficult to imagine no other player playing in the same scheme but not coming remotely close to David's numbers. David seemed a law unto himself, and more often than not, he made the critical plays when he needed to. But he seemed to do it outside the system.
