Your argument is strong and it is probably worth a try but it seems that Monty is sending a message that you need to have a consistent effort in doing everything else if you aren't lighting the lamp.
I hope he snaps out of it because he shows flashes and then fades. Contrary to popular belief, I don't hate him and I am not rooting for him to fail. I want him to play consistently no matter what line he's on and I loathe all the excuses (not by you) used to describe his play. I was just as tough, if not worse on Ryan Spooner than I've been on Jake.
