It's hard to see any way that Tebow will stick around in New York in 2013 unless Ryan is fired. Tebow is due $2.5 million next year, which doesn't sound like much for a backup quarterback, until you realize he's a backup quarterback in name only. If the coaching staff won't play Tebow now, this late in a miserable season, they'll never have a use for him.
Tebow could wind up being released or traded for a late-round conditional draft pick. Crazier things have happened than Tebow having another chance to start elsewhere. (Like Tebow's 2011 season when he led the Denver Broncos on an improbable playoff run.) But this year with the Jets has proven to be a big setback in Tebow's career.
