Mehta is not very well liked, but at least he's a Jets beat guy unlike Glazer. Mehta would be more "in the know"
..if I'm Idzik, I want to keep Rex around for another year or two, because it extends my own lease with the organization. I can continue to build my team, while flying under the radar of a head coach that takes all the blame from the media. Rex is the perfect scape-goat for Idzik.. why would he want to lose that?
Think about it fairly.. let's hypothetically say the Jets lose to Miami, and Rex gets fired. Idzik picks his own HC, and spends a fortune in the offseason for him. He trades for top level talent for his HC, he lets him have pull in the draft. He even gets him a real QB in Jay Cutler. He builds the team that Rex always wanted. BUT.. the Jets still finish 7-9 in 2014. (or worse) Their defense which for 5 seasons has been Top 10 under Ryan, slips to 19th. What if they only make the playoffs once in a span of 5 seasons.. or worse, what if they don't make the playoffs at all!? Meanwhile, Rex Ryan goes to another team and does well. Who looks like a jerk at that point??
At this point, the next Jets HC (again, this is over the span of 5 seasons) would have to play 6 playoff games.. make the playoffs at least twice.. have a top 10 defense every year.. advance to 2 AFC Championships.. have only 1 losing season.. and win about 50 regular-season\postseason games altogether, to be considered an "improvement" over Ryan. Pretty lofty a resume no?
Wouldn't it make more sense to fire Rex after he REALLY fails? Like if he had a 4-12 season.. so that even if the next guy went 5-11 the following year, it's still an improvement?
