Jae has always been a good - and at times VERY good - defender.
Vince had a great game. No worries for Jae.
CLE is trying to win BUT at same time trying to tread water for when "IF" they meet GSW - provided they get by US and TOR and perhaps WAS.
I can see them trotting out a Defensive lineup of
LeBron, Jae, Jeff Green, Wade and perhaps Thompson...when that lineup is engaged they are VERY good defensively.
Between now and June they will need to get Tristan ready for such a lineup, though - dude looked completely lost in the Finals last year.
