After 10 weeks in the one or both of the top 25s, the University of Massachusetts men’s basketball team is unranked again after three losses in its last four games. With nine regular season games and the Atlantic 10 tournament still to go, the focus shifts to seeding in the conference tournament and making the NCAA’s field of 68. With 21 games into the books, UMass (17-4) has established some things, while questions remain about others. Here’s a look at the Minutemen as they hit the home stretch of the 2013-14 season. WHAT’S KNOWN UMass in good shape — If the current struggles are more of a hiccup than a collapse, the Minutemen are very much still in good shape to make the NCAA tournament. Depending on what website is replicating the ratings percentage index, the Minutemen are either ninth (, CBS Sports) or 11th (ESPN). UMass has lived on the bubble in recent seasons, but as of now that RPI would have it firmly in if the tournament field was selected now.
