I've read a couple of B1G previews recently that of course mentioned how much we lost (4 1,000 point scorers - 2 to graduation and 2 top 5 NBA draftees)
While this is obviously a lot to lose and replace, I think we can look to the 1989 recruiting class for insight.
In 1989 IU had 7 incoming freshmen that joined Eric Anderson, Lyndon Jones & Matt Nover. From 7 freshmen we ended up with 1 stud (Cheaney), 1 very good starter (Greg Graham), 2 situational players (Pat Graham and Chris Reynolds), 1 bench warmer (Leary) and 2 quitters (Lawson and Funderburke). The Team went 18-11 and 8-10 in B1G.
In 2013 my prediction for the 6 freshmen is that we will have 1 Stud (Vonleh), 2 very good starters (Luke & Troy), 3 situational players (Stanford, Devin Davis, Hartman) and no bench warmers or quitters joining Yogi, Will, Hollowell, Hanner and E Gordon.
I think next year's team has as much talent returning as the 1989 team had and I think the freshmen as a group can be stronger (although I don't know that Vonleh can duplicate Calbert's season or career).
I think next year's team has one more advantage at Coach. While in most situations Bob Knight has a serious advantage over Crean. However, handling Freshmen might not have been Knight's best quality. He managed to scare Funderburke off after 6 games and Lawson lasted only one year. I think Crean will do a better job dealing with young talent.
So can we do better than 18-11 and 8-10?
I'm hoping for slightly better than that.
