Sam, who caught the game-winning touchdown pass from quarterback Chris Rix in the final minute against Florida, admitted that "he (Bowden) was upset with me because he thinks I haven't reached my potential," according to the television station.
Sam entered his junior year with 24 career receptions for 320 yards and two scores. The 6-foot-3, 195-pound Sam earned the offensive award for most dependable receiver following spring practice in 2002. He also has battled injuries during his career and was hampered by a hamstring injury the second half of his sophomore season.
"He (Bowden) was upset with me because he thinks I haven't reached my potential....but there are a lot of things in the offense where we are not showing our capability and I don't want to sit for another developing year," Sam said.
"I had to make a decision and I made it and it's over with."
Sam's younger brother, Lorne Sam just completed his redshirt freshman season.
Sam also told the television station (Channel 6) that money played into his decision.
"It's weird because you want to play here your whole life and you get here and then you decide to leave," he said. "So it's something I had to do to benefit myself and make money while playing."
Last year, Anquan Boldin left FSU following his junior season. Boldin earned All-Pro honors with the Arizona Cardinals this season.
