Barkley is a guy who could not even supplant Mark Sanchez on a depth chart.
He was not on a roster in 2015.
He came in to the game and played exactly like you would expect anyone of that caliber and history to play. He was absolutely hideous. Mechanics, decisions... you name it, he sucks at it.
That is the frame of reference for your post- the lack of patience with a fellow of that quality will automatically translate to the same lack of enthusiasm for a top level draft pick.
With that in mind- would you be willing as a bear fan to take some whatever random jackass that is sitting on the practice squad of dallas right now behind Mark Sanchez and give him the keys to the Bears for a couple years?
Or- How about we grab Logan Thomas or Tom Savage and let them start next year? They were both drafted in 2014 in the fourth round... we should probably give them a shot, right? I mean, that is exactly the caliber of player you are whining about here.
I mean, you are probably right. Eagles fans will have zero patience for Wentz cause they didnt keep Barkley around to give him a shot.
Rams will never give Goff a legit shot because they didn't let Sean Mannion get a year.
Bucs fans will never tolerate winston because Glennon should have gotten a few more years.
Titans fans will never give Mariota a fair shake because Mettenberger didnt get near enough time.
... Your premise is about as stupid a premise as I have ever seen... Fans wont give a fair shake to a first rounder because they are unhappy with a fourth rounder off the scrap heap!
