I don't think there was any way of knowing what the results were of Daunte coming back until we put him back in the game. During preseason, we didn't have the pressure that we saw vs. Buffalo, Houston, and Tennessee...except in the Tampa game when Daunte got sacked twice in one drive. But, Joey also got sacked once in that game...and it was pretty clear the OL was the main problem.
Then the Pitt game happened and it really didn't look like there would be a problem. It was a lot like the NE game in that it looked like a lot of things combined for that loss, but really pass protection and Daunte's lack of mobility was not one of them. Daunte got sacked one time before the final garbage drive, and on that sack Darian Barnes completely whiffed on Joey Porter coming off the edge.
So we were kind of sucked in to not realizing that we had a serious issue there until after the Buffalo, Tennessee, and Houston games. After Buffalo you're like wow, that looked like a serious issue in that game...but we've only had one preseason game where it looked like an issue and one regular season game vs. one preseason game and one regular season game, so let's move on and see if it stays a factor. Then in the Tennessee game we had similar issues...but we won the game. In this case yeah maybe you could have concluded that Daunte came back too early but it would have been hard to sell sending Daunte back to the training room after a victory. Houston game came and went, same problems, very close loss...we made the move.
Like Saban said, you have to account for the possibility that they did do everything right, but in the end they just needed more time.
It's one of those things you don't know until you get the guy into the live fire situations. You can't simulate it. It's like when I'm trying to evaluate the impact of trading costs on an equity strategy, you can estimate the broker fees and custodian fees and stuff like that and you can use sophisticated systems that give you a roundabout estimation of the cost to trade into and out of a position but you really don't know until you trade the damn stock.
