Don't we technically have a top ten player at each position (except PF) moving forwards with this team?
Assuming Lowry can stay healthy, get more involved as a scorer like he was in Houston and get back to the 15-7-5 on 55% TS (which is basically what he put up in 2011-2012 and he was splitting minutes with Dragic), isn't a he a top 10 point guard? He's also among the best defensive PGs in the league.
The only PGs you can say are out right better than him overall are (no particular order):
And I guess you could argue Jrue Holiday is better, although I'd disagree with that, he basically made the all-star team by default and his TS% is below 50, his PER is pretty low for a top PG at 16 and he turns the ball over at a high rate.
DeMar is quite obviously a top 10 SG, the only debate would be where he ranks from 4-10 after Kobe, Wade and Harden.
Rudy Gay is the 5th best SF in the league after LBJ, Melo, KD and Paul George.
Jonas Valanciunas has the potential to be one of the best centers in the league.
I'm not sure if this is even relevant really, but I feel like adding another top 10 player at the PF position (which is possible in 2015 when we have about 20M cap space, assuming Lowry/Gay are extended for a combined 25M per year) would make this team a pretty strong contender.
