^interesting chart showing who he compares most to physically and athletically
not greatest list but McNabb is on it. also if look at list Fields is most impressive out of them all when project him to NFL. mainly cause he can actually pass and make reads and timing throws. unlike a lot of guys on list just used their legs mainly in college to dominate. Vince Young prime example. never was a very good passer and terrible side arm form. got by with it in college of course but had no chance in NFL. he also wasn't that fast actually and in NFL his running game would be gone.
the rare combo of elite speed with a very good passer is what sets Fields apart and makes him almost impossible to compare.
