Minnesota, Indiana, Maryland, Michigan State all have more individual talent than RU put on the floor this season. It is not to say it was a large margin or difference but coaching/system and matchups are what usually are small separate items per team....
Indiana lost 3 times to Rutgers.
Indiana beat Iowa twice....
Iowa beat Michigan State twice....
RU beat Minnesota twice....
RU and MSU split 2 meetings.
Maryland beat Minnesota twice....
Maryland beat Michigan State twice.
Minnesota defeated Michigan Iowa and Ohio State (RU, Maryland, Indiana and Michigan State did not do much against those 3 teams).
All of these criss cross matchups are either drastically different matchups or huge coaching discrepancies. It is not a much coaching as it is how your best players style of play, impacts your team over an extended period of time. If your best player is a guard and is dominating the ball and taking the most shots, you have very little chance of winning against similar competition or better teams.
