I don't really follow football so I don't know what the standards are, but I doubt he'd have gotten to the place he did if he "sucked".
He was one of the best college players of all time. His skill set works great in college ball.
The problem is NFL football isn't just college football with paychecks, especially for certain positions, QB being one. In college, Tebow could run at will and with his build (more like a fullback than a pro QB) he could run over college defenders. That tactic isn't effective in pro ball for lots of reasons, for one, the linebackers defending the run are much faster and bigger. They won't be run over the way some random skinny defender from Butt State will, and defensive lines keep gaps much smaller.
Also the nature of passes are different in a spread offense vs. a pro style. Tebow was a very efficient passer in college stats-wise, but that hasn't translated because... you just have to watch the guy. His wind up with the ball takes forever before throwing and his mechanics are high school style. Even during the Broncos' win streak his throwing was legendarily abysmal, and even then there were a high percentage of dump-off tosses and screens which are comfortable, high-percentage passes that are easy to make.
Because of all of that, and all of the rule changes they've implemented to favor NFL receivers and QBs, passing is the most efficient means of advancing the football in the pro game. An NFL QB needs to be effective passing or the team will be unable to leverage their skilled receivers and spread defenses out (to have room to work and make them defend a bigger area). And when not threatened by the pass, defenses move more players into the box and jam up the run game further. He's horribly inaccurate and slow to throw, and despite his running awesomeness in college ball he's turns the ball over too much running in the opportunities he's had.
What really got him where he is today was Josh McDaniels' horrible draft pick. At best he was a huge project pick you'd spend a 5th on, maybe a 4th if your board is dry. Last year he had a stretch where the Broncos won games, but in nearly all games the defense should get that credit. Denver scored 13 and 18 points per game in 6 of the 8 Tebow-led wins, including defensive and special teams scores that he had nothing to do with. His best game was probably the win versus the Steelers, where he completed all of 10 passes. And after the win streak ended and the defense slowed down, they lost 4 of their last 5 with him where he was a turnover machine - people forget that part.
He came into this year with the Jets a 2-year vet with starting experience, and looked atrocious in preseason, even against scrubs and camp bodies. I've seen zero development of his QB skills in 3 years and he hasn't played any other positions. Broncos didn't compound their mistake and let him go, now the Jets will, and I guess he's off to Jacksonville to sell a few seats on his way to the CFL.
