Yeah I agree he sucked in Houston and I don't know what game or in what kind of state DW Toys watched that game, Houston were never on it even when the Patriots were shooting themselves in the foot.
But, he played Ok in Denver in that system, mechanics a part, at least from a pressure perspective. In Houston though he was like a deer in the headlights. We don't know what happened indoors, maybe he was under a lot of pressure from the ownership because of his contract, maybe BoB somehow ****ed up early approaching him like "Look kid, nothing against you, you are not my guy, you are a Rick Smith hire, but since you are already here let's work this out". You say this thing to a guy mentally strong and he will make you eat those words, Osweiller may have crapped his pants, of course, all speculative here, but considering that right now BoB has mismanaged his QB situations many times I don't doubt he somehow ****ed this too, he's a good coach, but he needs to prove he can manage the QB situation, so far he messed up everytime he needed to step up.
So obviously after a frustrating season Houston didn't insist in that mistake, they were 100% right this time, it was going to only get worse, but that doesn't mean Osweiller can't work out elsewhere, by work out I mean being a game manager in a team with talent distributed in other positions.
