The bolded is very true, and its why I don't understand why teams hang on to bad quarterbacks who were ostensibly good prospects. How often does a QB who doesn't show the ability to be a top quarterback within their first year go on to become a good quarterback? Practically never. As for Mallett, I hated it at the time because I really wanted someone else. But it was a prudent idea to try and squeeze him into draft picks - the climate after the Kolb/Cassel trades really turned and made it impossible.
