Agreed. He's at least as good as Tyvon Branch when healthy. The injury history is a bit daunting though so as mentioned the Jets will need to be protected and build in the incentives in his contract towards a full game season.
Oakland couldn't move Branch for a 5th rounder even if they wanted. Bad contracts do not set the market. He was a tagged player they are tied to right now for more then his worth. He will likely get an extension this year just so Oakland can get a little cap back. Landry is an average S that is above average money.
