He's into is late 20's now though. The soonest I could see him being major league ready is at least five years from now, and that might be a stretch considering most prospects take more than that- and they're starting from a better point than Tebow is.
He hit a pretty big bomb, 400 something feet, in his showcase but he also got jammed in BP- twice. I thought his hands looked slow and his swing was very choppy. Not many guys can really alter their swing plane once they're into their 20's, especially late 20's like him. I'll be shocked if he ever makes it as a solid AA/AAA player, let alone major leaguer.
He could make for a good locker room presence and role model for youngsters though.
