I follow the draft year round, he was a guy who was undervalued and rose in the last few months when, as I mentioned above, the talking heads could not ignore the reports of team interest in him.
Prior to that point he was listed consistently as a late first to early second round pick, a "second tier" type of guy that was not in the elite prospect range.
Same thing is going to happen with other prospects this year, happens every year. Guys get undervalued but as the talking heads realize they had it wrong they correct and align themselves with the team boards. Among the QBs that is going to happen this year with Petty. All we hear is 3rd round, that is going to change dramatically. Plus of course you have the fact that QBs tend to be overdrafted as it is.
