A word used to describe an athlete who, while talented and/or puts up respectable statistics in their sport, still totally sucks ass. Whereas an athlete with an 'intangible' quality normally is though of as someone who brings something special to the game, an untangible performance\performer is one that's relatively solid statistically, yet did absolutely nothing to help the team achieve a win.
FAN 1: Goddamn it, the Vikings got Brad Johnson back
FAN 2: Yeah, but statistically he has more 60% completion games in the last decade than any other QB!
FAN 1: Yet he still blows ass. He only excels in those kind of untangible qualities that don't really help when the game's down to the wire. He's like that douche Drew Bledsoe that way.
