Are you wanting me to tell you what plays they are running? If that's what you mean by system, I can't do that. I see a variety of offensive sets. Again, I am no savant so can only paint in the broadest of brush strokes. Like many teams in the B1G, I have seen some motion, some flex, some pick and pop. As to specific nuances, that is for someone with a lot more knowledge of the game than me.
What I can see is what Johnson has shared in several interviews about his vision for the team. This is a team that is hard-nosed and competes until the final whistle. I can not remember a time where I have seen a player take a play off whether up 20 or down 20. They may be over-matched at times but they don't seem to be out-worked. Ola-Joseph guarding Edey was an example of a player giving his all for the team.
Johnson was very enthusiastic during the off-season when describing the length of this team. I think that he expected more points in transition as the players jumped passing lanes leading to easy baskets. Unfortunately, the team has struggled with missed assignments, reaching, and getting smeared out on screens.
