You guys are all hitting on the right questions. NWAkron points out that stiff defense is our only route to victory, especially on the road. Last game we produced 6 points total from the center position. The rest of the MAC can read box scores too and that just adds more stress on our guards. When the Zips are on the same page defensively they are actually quite good and their Kenpom ranking (#57) bares that out. But they do have mental lapses and it's very frustrating to watch the opponent drive the lane untouched. But not only do I see "Angry Groce" flare up, but LCJ is starting to take over this team and holding teammates accountable. They know what needs to be done, but they are lacking consistency.
If we are locking down so tightly on defense then we can not afford to take chances. I love the transition game, but most of it comes from steals from jumping the passing lanes. I am not seeing the guys gambling out there at all which is likely a coaching decision. It is very much like a defense in football ball-hawking when they are up by a comfortable margin. We do need to do a better job blocking out and everyone needs to put their body on their guy, but with this offensive style there is not going to be someone staying home under the rim to rebound. Our center on offense should be all over the court. For example, when Ohio had their run in the Tourney their starting center was 6'-8", Ivo Baltic, https://www.youtube.com/watch?v=alFzurcDB0E and you will see a similar skill set in Luka Eller, https://www.hudl.com/video/3/6276902/5aa83507478e590ee078ac4d a recruit who Groce is pursuing as part of his 2020 class. I will now go and give myself 1,000 lashings for linking to anything Ohio related. Please forgive me.
Edit: I should add that our approach on defense, both attacking passing lanes and hitting the boards will have a lot to do with the opponent. If we are playing a team that likes to run themselves then you have to choose your battles and it often means prioritizing getting our butts back on defense asap.
