Iowa is (at least) 5-0 in games that were most likely losses in recent seasons.
@ NW
@ PSU
vs UM
@ IU
vs NW (but only because of being down by double digits for a lot of the game and needing a buzzer beater to pull it out)
Those 3 road games - in recent years' past - were huge hurdles for the Hawks and they usually stumbled. I include Michigan because of their record and rankings. These 5 games are the difference between being a 5 (possibly even a 4) seed right now, and not wherever they'd be if all these results were the opposite.
Defense could stand to get even better (always), but this team has got guts and so many offensive weapons, both potentially and reliably - and it could be a different number of guys every game. You try to take away JBo & JoeW, Cook & Garza will get you. Limit the frontcourt? The backcourt will drain perimeter shots. So many options, and impossible to stop (unless the team is incredulously missing all the bunnies like they were vs NW).
Personally for me, its just an almost complete 180 of last year, at least in terms of results and the excitement for the program.
