TAMPA, Fla. — Malcolm Glazer, a self-made billionaire who shunned the spotlight while leading the takeover of English soccer’s Manchester United and transforming the NFL’s Tampa Bay Buccaneers into Super Bowl champions, died Wednesday. He was 85.

The reclusive Palm Beach businessman had been in failing health since April 2006 when a pair of strokes left him with impaired speech and limited mobility in his right arm and leg.
