Most of the analysis I saw last night said that Fields and Jones were decent picks at where they went, but there are some big question marks surrounding both. Fields at least should get a year before he needs to start (unless Dalton gets hurt). Jones might be thrown into the mix more quickly. There are some concerns that Jones isn't quick enough for the NFL game but we'll see.
I'm most intrigued by Trey Lance, I know he was great in the FCS, but the FCS talent level is nowhere near that of the FBS. Other than Carson Wentz, I can't think of a FCS QB who had success in the NFL.
