It's clear they want nothing to do with Tebow.
Unfortunately, it's not really "clear". The last few times they could possibly have pulled Sanchez, Tebow was injured with cracked ribs. He wasn't even on the active roster this past Saturday. The only reason Sanchez wasn't pulled on Thanksgiving was that the Jets (stupidly) didn't even have McElroy active when they knew Tebow was injured.
About the only thing that is clear is that the Jets are incompetent. I predicted at the beginning of the season that Tebow would be starting by week 6, at the latest after their bye. Well, that didn't happen (they were 3-3 at the time) and the Jets went on to lose all of those games.
