That's my whole point. Its all assumption. Rettig couldn't have been worse? You sure about that? Heck, are you even sure that Rettig has a stronger arm than Laviano? I actually tend to think actual arm strength had nothing to do with it, but rather that Laviano had bad mechanics, which he failed to really improve with any consistency. Another large aspect was that whomever was in at QB was likely to be hit very hard, repeatedly due to the O line issues. Laviano took a beating, and generally made either a decent decision, hung in and threw only to get pounded, or took the sack without fumbling. If Rettig was likely to cough up the ball in a strip/sack scenario or make Nova-like decisions in the face of a sack, should he still have seen meaningful time? Those kind of issues will kill a team very quickly. Unfortunately, sometimes "ineffective" is an upgrade if the other player is likely to commit turnovers. BUt what I was really saying is that no one knows the reasons, and whether they made sense or not.
