To your point: HB, Fox, and Buddy were 4th, 11th, and 20th IN THE ENTIRE LEAGUE in mpg last year. 3 guys in the top 20 league-wide. That's absolutely ridiculous, especially given that HB was often bodying bigger guys defensively and DFox plays such a high-energy offensive game.
No, Luke didn't have much help off the bench in the first half - and many on this board wanted to crucify him for playing the one guy (Cojo) who got consistent min off the bench. But he should have avoided that load on those 3 at all costs. Not only will Luke have a deep bench this year, but playing the hi-energy style on both ends they need to play will demand that he use it.
