The product on the field this past year was...not encouraging. At all.
Streeter's missed on - or completely failed to develop, which might be worse - the last three QB's he's recruited. DJU regressed badly and lost all confidence. Phommanchanh was a complete bust. Bubba Chandler decided to go play baseball instead...which begged the question, why on Earth was Streeter wasting his time and a precious QB slot on a guy who might not even come at all? We're Clemson, we'd just had the #1 pick in the draft, we didn't have to gamble but he gambled anyway. And lost.
Getting what amounts to zero out of a 5-star (DJU), a high-end 4-star who was the #1-rated dual-threat QB in the country for his class (Phommanchanh), and a no-show for your last three QB picks is...bad. Like, dismally bad.
In most professions, Streeter would be out the door. That production certainly will not get him promoted.
I can't think of a Clemson QB that has improved during his time at Clemson since Tajh Boyd. Deshaun, Trevor, and DJ all regressed their 2nd year. Trevor should have had two NCs and a Heisman. We'd had pretty highly ranked QBs come in and look lost.
I'm not saying that's 100% on Streeter, but something has been wrong on the offensive side for years.
