There's no point in even comparing him to Tomlin and Belichick. You can't look at the Jets through a microscope and single out any one person... Rex Ryan, Mark Sanchez, Mike Tannenbaum, or whoever else is getting blamed right now.
Every team is a sea of moving parts all of which contribute to the greater success or failure of the franchise. While the Patriots have the "ideal" configuration of having its two major points be its HC and QB, it isn't everything because the smaller pieces need to do their part too. If the Patriots smaller pieces were doing their part, the Patriots would have won even more Super Bowls since their last.
Right now the Jets have numerous problems going all across the map. There is no silver bullet to fix this team. Firing Mike Tannenbaum won't save the Jets. Firing Rex Ryan won't save the Jets. Cutting Mark Sanchez won't save the Jets. The Jets are a big stinking mess right now. They are toxic.
Organizationally, a decision needs to be made whether to try to cut out the fat and improve across the board over time, or to just blow the whole thing up with an atom bomb and start from scratch. The fact that the Super Bowl is going to be in NY next year leads me to believe Woody J will hold off on using the nuke one more year at least.
So moving forward into next season, out of all the problems the Jets do have, Rex is lower on the list than say Tannenbaum and Sanchez. Again, we're not going with the nuke theory so changes are only going to happen in limited areas. Rex will survive this debacle, and there's a strong chance Sanchez will too because of his contract and the fact that there's unlikely to be a "franchise QB" in this upcoming draft that's worth making an investment in.
If Woody drops the bomb then all bets are off... otherwise you need to gauge where to sit pat and where to cut to improve for next year... Rex will stay.
your right there is no reason to compare him to tomlin or bellichick, just like there is no comparing him to joe walton. peoples reasoning for keeping him around cant be that he has been better than bruce coslet.
it has to be things like you pointed out.
i could see it going either way, i could see them keeping everyone involved and trying to add some pieces to fool themselves into thinking they could make a run at the sb next year in metlife.
i could also see tanny going because of his terrible job putting talent on the field, rex going because of his apparent total lack of control.
its really all up to the guy that scares me the most... woody johnson, he has been quick with the trigger in the past but has also at times been willing to let things go up and down in mediocrity.
