I mean Wins against PSU - who everyone though would be good pre-season, Rutgers - who has looked pretty solid in the games they've played, and now Michigan - who I guess is bad?  Either way they deserve to be ranked 3rd in the B1G.
Hoosiers remained in the unbeaten group this weekend with a nice victory over Michigan. Nobody would have predicted Indiana could start 3-0 in a season that saw early games against Penn State and Michigan. Unfortunately those teams haven't really shown up either and their best wins are 1-2 Rutgers and 1-2 michigan. Penn State is 0-3. 
I've got Indiana a lot lower than the AP poll, but honestly they seem to have three wins against teams that just aren't that good. The fact that two of them were overhyped has carried them further,
