I don't think he is better than any of Iorfa, Hause or Batth. At absolute best he's on a par with them, that's when he's playing as well as he can which is never a given being as his performances vary wildly in quality from week to week. He is better than EEL, but you don't sign someone because they're better than your fourth choice (potentially fifth if we played CBJ in the middle), you sign players who are demonstrably better than what's currently in the team, like we have with every other position.
