I guess I don't see this being as big of a loss as some others do. I definitely would have preferred to see Mussini stay but I don't think losing him changes all that much as far as my expectations for the upcoming season. In order for this team to take the next step the number one priority will be being much better on the defensive end and as much as Mussini improved on that end last year he is still a liability there.
I also don't understand the fretting surrounding who the first guard off the bench will be. We still have a ton of lineup versatility in the backcourt even without Mussini. I figure all 3 of Lovett, Ponds and Simon will start and at least 2 of those 3 will be on the court for the vast majority of games. We then have Ahmed, Wilson and Clark that can all play the 3 when one of those guys is on the bench.
I like Mussini and wish him well, and do hope he would have come back for one more year but this is not the end of the world. Let's not forget that in our two most impressive wins last year (@Syracuse, vs Butler) Mussini didn't play at all.
