Wow! That is something. One of the reasons I said Sam may have the most long-term upside of all the QB's in this draft.
As to Cleveland, keep in mind they could have Tayor (Rosen or Darnold) really impress in the pre-season, draft Barkley as well, they now have two excellent receivers, and Myles Garret should be completely ready to go at a top level, and the team still would have several holes to fill. They need an LT, they need help on the defensive line, especially at DT, someone who can stop the run. They need LB help, and they badly need secondary help. Plus they're not very deep anywhere. The Browns have had a pretty good FA, and have a lot of picks in the draft, but they are still going to lose a lot of games this year. As I said before, 6-10 might be a "successful" season for them. They are so thin at DB, I'd not be surprised if they took Minkah Fitzpatrick at #4 instead of Barkley, or trade down to get badly needed help there, and at OT, but this isn't a thick OL class.
Agree with on3@my that there are maybe a handful of top tier NFL QB's, and the rest are not, and Taylor is in that not. I'd say Brady, Rodgers, Brees (small gap) Ryan, Roethlisberger, Stafford, Wilson (another small gap), Rivers, Newton, maybe Wentz, Goff, Carr (still too young to really say). I'd say those 12 guys jobs are really secure. Everyone else you can move around, which shows why Alex Smith, Kirk Cousins and Tyrod Taylor played very well last year, and just switched teams anyway. Garoppolo and Watson may ultimately end up in tier #1 as well. Prescott, Winston, Mariota, Dalton, can all play well, but aren't in that top tier, and may never get there. Same with Bortles and Keenum, really.
There's a pretty good chance in a couple years we'll see Rosen, Darnold, Mayfield, Allen starting for teams. Lamar Jackson too.
