If you compare Tebow to Manziel you know nothing about football? Did you even play past high school? I will mark this thread and remind you in about 8 months. Manziel can throw the ball you dumbass
tebow didn't have the mental ability to process plays fast enough. He did well when defenses didn't look out for him - in that first month, guys would be double teaming the deep receiver, believing he could actually hit them on passes. Once they learned he was inaccurate, they started attacking him and his run was very ineffective suddenly.
Manziel is short. He's lazy. He gets over-emotional and taunts other players on the field. Off the field, he broke some rules with autographs. He was drunk a lot, and he's underage. He showed up for Manning QB camp still drunk. He's fast but 2 steps behind all the new good QBs in the 40 video compilations. He ain't RG3 when he turned on the jets.
Tebow was a one-sided player (granted, he ran OVER people instead of around them like manziel). But once the defenses attack him and put a few licks on him, he'll be ineffective. They have that in common. I'm not talking personalities, Tebow is simple and has a big ego, but he wasn't drinking and breaking law like JM.
