This is a really, really dumb thread. First off who ever said Mitch McCarron was a marquee player? Secondly, is he even rated that highly compared to what he actually does? Solid, reliable player who plays both sides of the floor, makes great reads on offense, and makes big plays on defense, Australian, not a star of the team but does all the one-percenters well - that's what Mitch mcCarron is and those are the skills regularly attributed to him. I can't see how you can read that, see Mitch McCarron and say he's therefore overrated.
As for 400K, it sounds unlikely but we don't actually know what players are being paid in the NBL at this point. That definitely would have been import money in recent seasons but if someone is paying that, well, good luck to them I guess!
