I guess my previous response/joke about coffee was too harsh for some and deleted. Let me restate in a more amenable fashion;
Going on an internet sports message board and claiming to be an expert with years of experience that only uses reason to provide insight does not move the needle because anyone can say they are anything here. There are no background checks.
Your opinion regarding the potential of the two QBs in question does not line up with a lot of Saints fans and most of the analysts that get paid to share their insights regarding NFL QBs. You can certainly think that Hill has the most potential and best chance to be great, but that looks like it comes from personal bias and not the pure unemotional reason you infer.
Quite honestly, the NFL world of players, coaches, media and fans will consider it a major upset if Hill wins the QB job, because most of those people see Winston as the better QB now and the one with the most potential to improve. Does not mean they are correct, but that is the consensus.
