Ulis being 5'6 155 lbs and performing, fighting, defending, and controlling the game the way he did is exactly what makes him tough, Wayne. There's really no argument even out there that he wasn't a tough guy, assuming you're talking about basketball tough.
There’s just no intimidation factor there. Yeah, he was tough in the “aww, look at the little guy go” sense of the word tough, but not the “I fear this guy may punch me out” sense, which is what Bledsoe had.
