Are Morneau's Injuries Taking Too Much Toll on His Body Preventing His Return to Greatness?

A few years ago, Justin Morneau led the Twins in power, taking home one MVP award, averaging over 100 RBI and 30 home runs. He was one of the feared sluggers in the AL. But now three straight years he has lost significant time to injury. He was only hitting 225 with 4 home runs and 21 RBI before this latest trip to the DL. Will he rebound and get back to his previous form? Or are his best years behind him?
