That’s what would worry me as a ISU fan. We don’t start a guy that’s shorter than 6”6, and I believe you have two smaller guards.
I've seen this a bit from Illini fans on line. Tamin Lipsey is 6'1" and Keshon Gilbert is 6'4" - but neither play as "smaller guards". They are both VERY physical
The guard length can cause problems on our offensive end, specifically preventing Lipsey and Gilbert from either getting to their spots, or getting shots / passes off from those spots. But on the other end, I have no concerns. They are both very strong and don't shy away from contact.
I'm very curious to see how we defend the Domask "booty ball" thing, and whether it works at all. My understanding is that Domask, as more of a 6'6" SF than a PG, "posts up" the opposing PG at the 3-pt line, and then backs them down toward the block while the other players run motion and then he either scores or passes out of it to a spot up shooter (Shannon) who can shoot or drive. I don't think he's going to be successful backing down Lipsey, regardless of a 5" height advantage. Tamin will hold his ground and either keep him up high, draw a foul if he's leaning too hard, or swipe the ball. Some of the analysis talked about the double coming when he backs down - but I don't think that's necessarily a given. Tamin won't let him get or turn middle, and if he goes toward the baseline the hard double will come, but I think they'll let him go 1:1 while he's out by the 3-pt line.
that will be a fascinating part of the game to watch
