His arm is "fast twitch" strong. I know it is cool to think he is overrated. The only guys that would not say that he could be excellent are pretty negative thinkers, because that is always the "cool way" to give an opinion. Remember, Ian Book wasn't going to even get drafted, now the Philly coach says he is the smartest QB he has ever been around. Another thing is the "cool" glass argument. The injuries Buchner had previously are flukey types,(ACL, Shoulder driven into the ground) if he had something like a chronic pulled hamstring than maybe the "glass" thing would be true. I guess Jalen Hurts is partial "glass" too because a guy tackled him so his shoulder was driven into the ground and he had to miss three games. Well Buchner was hit in a worse way the second game. than Hurts was on his injury.
Stats are very overrated and you have to look at circumstances. I haven't seen a QB stand in tough, knowing he was going to get killed, and not change his staying strong to complete the pass downfield like Buchner did against South Carolina. Or change the release angle on a long pass and have it hit the guy perfectly. Our line was horrible the first half. It always come down to the line.
Could his touch be better on the short stuff, yes, but he is pretty darn good on the long ball and the longer down field balls. Line protection will always be the key and possibly having a system where he drops slightly further if the blocking breaks down.
