UTSA won 12 wins last season so I'm not sure what "improved a bunch" means for them.
Too early to tell on Rice, IMO. Sometimes teams just match-up well against others. Rice also beat Louisiana Lafayette who went 13-1 last year and won 10+ wins for 3 straight season but they have a new QB now so who knows what they really are this early in the season. Rice has mostly been rolling with the same QB this season, though.
