The defense is an issue, but I think you would see CJ become a lot less effective without Lillard drawing doubles and the defensive focus.
Counterargument to that is McCollum balled out when Lillard went down, but their schedule was charmin soft then as well. They would be better served beefing up their frontcourt defensive presence, I think. Breaking up a backcourt that effective on offense, it would be hard for them to get better on balance.
It's hard to say. Portland is in a bad situation with their salary bill being so high and the amount of holes in their team being so high. I want CJ and Lillard to succeed, but it's looking like they need a trade to change up their roster and the only valuable and IMO expendable piece is McCollum. Nobody is taking Evan Turner's contract.
Did y'all see the Knicks tweet about the Oakley situation? Wished him luck with his arrest and to "get well soon", basically implying he has mental issues. Fucking classless.
