His back derailed his career. Sure he could have developed his offensive game better and been more dominant but not many have done better than him.
Here's some other noteworthy guys and how manyb1st team selections they had:
Stockton 2x
Bill Russell 3x
David Robinson 4x
Charles Barkley 5x
Derrick Coleman(the man you compared DW to be more disappointing) 0x. also only 1 all star and 2x NBA 3rd team.
