It's a strong class, certainly stronger than 2016.
Will all 5 succeed? Doubt it because it is just as important the situation the rookie is put into. That was the best thing Prescott had going for him and the same for Marino and Rothliesberger, although they were 1st rounders. But they were not in the top 5.
Lawrence and Wilson will be playing for bad teams, SF is in the best division and the QB with the best chance for early success will go to NE.
There are still ?'s about Darnold, Goff and Wentz and they were all top picks in their drafts. Is Tua going to make it in MIA? How about Jones in NY and Hurts in PHL?
The bottom line is every GM has to keep taking QB's until he finds his. Even if he has to do it every 2 years, they have to find out fast, not many teams like GB grooming QB's. In fact, none but them.
