This team just shows how open minded Matta is as a coach. He has a team that doesn't have a superstar, doesn't have a lot of strength/muscle (several players with slight builds, but a lot of length), and he will find a way to get that team to be a contender in the B1G. One of the things that gets overlooked about Matta is he does an excellent job of featuring star talents and building the team around them, really a better coach for a 1 & done player than many out there would be. But this year with a team of many guys at a similar talent level, they're opening it up and playing more as a team.
I could come up with 10 good reasons to go zone this year for this team, but I'm not going to make guesses about the main reason why when I don't know. But I will say that with the emphasis on freedom of movement now in college basketball, it's not easy to go through a season planning on playing tough m-t-m D when you know the refs are inconsistent (sometimes wildly inconsistent) from game to game about what type of contact is allowed and what you are allowed to do defensively. Suffice to say this team is in the early stages of the season with a lot of freshmen and a new style of play, so they will improve in almost every facet of the game from here forward, including defense.
