My instincts are to go with the senior to match the other guy's IQ. My senior is also rated higher in DEF, REB and BLK. Opponent's player is listed as a SF, both mine are PF. Matchup takes place at the PF position. My worry is the huge ath difference between my senior and the enemy. This is what makes me wonder if I shouldn't give my athletic guy a shot, IQ be damned...
tl, dr: What is better for defense - DEF/SB and IQ or ATH
