Tebow threw 14 passes, only 4 of which were caught. That gives him a total of 13 completions in 36 passing attempts over the course of 3 preseason games.
Of course, preseason games aren't completely indicative of what will happen in the regular season, but individual performances can usually be evaluated pretty well.
There's no way about it... Tebow has been an awful passer. This is nothing new, for anyone who has been paying attention. He was a poor passer in Denver, even when the team was winning games.
At this point, the Jets' insistence on giving him the ball is to their own detriment. Fellow backup QBs Greg McElroy and Matt Simms might be viable options to be the Jets' 2nd QB behind Mark Sanchez, but they haven't been given a real opportunity to show their skills.
If Sanchez goes down at some point, the Jets will be in serious trouble. It might be some people's dream, but the Tim Tebow era in New York would result in one of the most atrocious offenses in league history.
Guyism summed it up pretty well, with the following two GIFs, which demonstrate the best and worst of Tebow against the Panthers:
In the first one, you can see Tebow doing what he does best: making something out of nothing, and running for a 1st down on 3rd and 16.
In the second one, you can see what Tebow does worst: Throwing the football.
There were no Jets receivers in sight. He just threw it straight to the defender. His accuracy is obviously an issues, but this was more than that. This was horrible decision making.
When you look at these two plays, along with the rest of his NFL career, it's clear that Tim Tebow simply isn't cut out to be a starting quarterback.
Maybe he can play tight end, running back, H-back, or something else. But this guy just isn't a quarterback.
We'll see how long it takes the Jets to realize that.
