If Hunter plays the "2", he is going to get abused. He is a Cline like player. He can light it up, but if he had to guard some of the elite scorers he will get carved up. Hunter could be a "2", but he is much better served as a wing and he will likely be the best player on the team next year (if he comes back). He is kind of like Mathias in that you can put him on the other team's best player and he will do just fine. Let the other team adjust on defense. With that said, if the other team's best player is a wing and Hunter is the "2", whoever IU has playing the "3" will have to guard a "2". Archie likes a lot of big players and it worked really well at Dayton. But with the well of talent IU can pick from, he doesn't need to do that. If it doesn't work quickly, he gone. There will be very little room for error this year with Romeo. If he doesn't make the post season with Romeo the pitchforks and torches will be out. I am not overly impressed with their roster, so I wouldn't be super shocked if they miss the tournament (but I think they will make it).
I not taking a side one way or the other on the 9 forwards argument. That is how Archie likes to play. But, Anderson and Hunter at the "2" is less than ideal. I think IU is 2-3 years down the road from having a shot at their lofty expectations.
Back on topic: Hall is a perfect fit for Purdue. Can't wait until the season starts. If the young pieces show what we expect, Purdue will be a very attractive landing spot. Purdue has had a player in the running for national player of the year for what will be the third year in a row (with two different players). That is very appealing and I love that Purdue has been in the national spotlight in a good way for the last three years. If they can have success after losing 4 starters/seniors, I think that bodes very well for convincing a player like Hall to hop on board.
