I don't get the whole "Young is the Mahomes light" idea. Mahomes is a purple unicorn. He can run around all over the place get hit and still make perfect throws because he has an arm that maybe only 1 other guy in the NFL has right now. It's a cannon. Young has no where near that kind of arm. The main reason that Mahomes can make those is because he has that arm. Young does not have anywhere near that kind of arm, it's not a bad arm it is just average, and people think he is going to be able to do the same things.
When Young reads the defense and throws on time he is as good as any QB in this class but when he makes plays off schedule he looks great, in college. What happens when he can't make off schedule plays in the NFL. He will still be good but he won't be what everyone thinks he is now.
If he was his size and had a Allen/Mahomes arm I could see him making those off schedule plays in the NFL. Or if he was 215 lb and had his current arm strength I could see him doing it. But at his size and his arm strength I just don't see it.
