It's funny that we have the opposite perception - things that get let go in the B10 are called in the tourney. And yes, having 18 teams is a lot to keep track of, even for us.
Defensively, I'd say we are fairly physical, but because (intentionally) we don't gamble on trying to force turnovers or block many shots, we generally commit fewer fouls. One of our coach's goals is to make more FTs than our opponents attempt (just missed out on that for the year, but it's really close). We are excellent at defensive rebounding, too, which limits opponents' second chance opportunities.
Offensively, I think it's a mixed bag from a physicality standpoint. Almost half our shots are 3s, and literally every one of the 9 players in the rotation will take them, including the two 7-footers. However, we also have excellent slashers - particularly Tonje and Blackwell - who draw a lot of contact, and may have gotten (earned) reputations as push-off artists. Crowl (one of the 7-footers) can be physical in the post on offense, but is often double-teamed. He actually leads the team in assists, but teams have been able to neutralize his scoring. The other 7-footer, Winter is more finesse - pretty good rebounder, though
I think your lack of size might be a blessing in disguise, because we might not be able to take advantage of that for defensive reasons. We may only play one big at a time other than at the starts of halves.
