I disagree, but I'll tell you why though. I happen to value spectacular up the middle defense ( maybe more so than most) and XB is less than spectacular. Offense-wise, you're right, he would be hard to replace. Also, Betts is 3XGG winner in RF and our RF is tougher than most. Betts seems like a consistent 30/30 and perennial MVP candidate. I love Bogey, don't get me wrong, but as far as absolutely must keep and retire a Red Sox, Betts is my guy.
