Speaking on the condition of anonymity, the source said the Texans have done nothing to signal a willingness to deal Johnson. But the source also made it clear the Jets aren’t looking to add Johnson at this point. "Clearly Andre is a special player, but special players come at a price," the executive said. "Right now, with the direction the team wants to go, it isn’t the best fit. While he is a tremendous talent, he would hurt a lot of cap flexibility."
With the Jets roughly $23 million under the cap and even more heading into next offseason, the flexibility argument seems pretty thin, even with Johnson's current eight figure charge. It's not like the Jets are going to have many opportunities to spend at this point.
I agree that Johnson probably isn't a fit for a different reason, though. He just turned 33 a few days ago. While he just had a 1,400 yard season, there is no way of telling when or how rapid his inevitable decline will be. It depends on the price, but it would be difficult to see the Jets part with a premium pick or picks for a player who would likely be a one or two year rental. At the right price, he would make sense.
I'm not sure it would be wise from a short term-long term cost-benefit analysis to give up more than a third. I'd probably do it, though, if the cost was that or less.
