I dont think any of the comments relating to Bateman have anything to do with his discipline.
He was not setting the world alight before we signed him and people thought he would magically arrive here and recapture his Raiders form.
He had a 750/800k contract for 4 years and hasn't delivered performances commensurate with his salary. At 400k a season, I don't think anyone gives a shit and we aren't having this conversation.
Defensively, you can't really argue that he has been solid, but a back rower needs an element of attacking threat which is where he let's us down. He's played 32 games for 2 tries and 3 line breaks. Sam Fainu outperformed him by far on less than half the money.
You can talk about being picked for Tier 1 nations etc. But Biden was also President of the USA...The title means nothing. Bateman is living on past reputation.
When you factor the cap space, roster space, performance and some issues with coach and various opinions on subjective matters, it adds up to feeling like he'd be better off elsewhere.
