Tebow has been very accurate in the few passes he's thrown this year. His two incompletions were a wide open drop, and a throw away to avoid a sack.
While true, lets not forget that just about every pass he has completed was for short yardage (if I remember correctly, the one 20+ yard pass on the fake punt was a short toss with a good run after the catch), and the sample size is ridiculously minuscule. He hasn't been tested through the air in really any regard worth judging.
Everyone in the AFC has clinched a playoff spot, it is just seeding among the division winners up for grabs. In the AFC the final wild card spot is up for grans (between Minnesota, Chicago and the Giants) and the NFC East (Dallas and Washington who play each other tonight)
