I see Haye destroying Roy at cruiser. This fight would play out similar to Meldrick Taylor vs Terry Norris. Roy was slightly faster than Haye, but didn't have the strength or punch to keep David honest at that weight.

Ruiz was a slow, plodding joke of a fighter, whose style is completely opposite of the athletic Haye. Roy was the definition of athletic, but his punches had noticeably less affect at 175, and Roy would've had to rely on speed and movement to win at cruiser. Haye had fast feet and hands, and while Roy would've been slightly faster, it wasn't enough to keep Haye off balance and at a distance the whole night. David by early stoppage/blow out.
