What's up y'all -- I can't guarantee I'll be particularly active here but I'm more than willing to respond.
Nagy's "inability to get Howard going" gets overblown. He was an outstanding rookie RB who seemed to be able to "just create yards" with his blend of outside vision and power, but fell off hard in his sophomore season. If you point to his 6th ranked 1122 yards, I'll point to his T-20th ranked 4.1 YPC, which in my opinion is dramatically more important than total yards anyways. Howard is a one-system back and Nagy doesn't prefer that system, and in these debacles the Coach will win. Every time. Especially when considering that we're talking about one of the most replaceable positions in football.
Also, I'm well aware that you can't "just break down a coach with one drive", I'm not living in fantasy-land. But I've yet to see anyone attempt to do any deeper study than just saying "he gets too cute" without any evidence, so I figured I'd pick his best drive (my opinion) and show how his playcalling has the potential to affect defenses without needing great individual play. Nobody in that drive does anything particularly spectacular, Howard grinds out a few good runs, Gabriel has a few solid touches, Josh Bellamy and Trey Burton each pick up first downs, and Trubisky throws exactly one "real" pass. With that in mind, it was a perfect candidate for a detailed pseudo-study.
Also, I'm a bit confused as to the criticism of Miller? He was productive, he had a team leading 7TDs and could've had up to 11 had Trubisky hit his marks. Are you of the opinion that he's in Floyd's category simply because he didn't stack up 1,000 yards? You're more than welcome to that opinion, but I think he breaks out in a big way next year. He ran too many good routes not to and got open deep too often -- I think you'll be surprised. Should end the season our WR2, with potential to become the WR1B.
