#2 1998 vs #3 1991
Starters and Bench
This match-up leans somewhat in the favor of 1998 from a talent perspective. While 1991 does boast some size that could give Antawn Jamison and Ademola Okulaja some trouble, the talent gap is a little wider at the other positions. 1991 also sports some significant depth at key positions making that team better able to weather foul trouble and fatigue. It also should be noted there is a team/toughness aspect to 1991 much like there was with the 1993 team. 1991 strikes me as a more cohesive unit and has a distinct advantage with Dean Smith coaching versus Bill Guthridge.
So on paper 1998 looks good I would expect takes a win here but 1991 has some intangibles that could tip the scales.
