Cam Newton allegedly stole a laptop while at Florida. He was temporarily suspended until the charges were dropped. But, he transferred to junior college anyway.
After playing one season at Blinn College, Newton resurfaced as a top recruit. He landed at Auburn where he began to put together a spectacular season that put him at the forefront of the Heisman Trophy race.
But it wasn't long before reports arose that Newton's dad, Reverend Cecil Newton, had possibly been shopping his talents to schools, notably to Mississippi State for an amount of $100,000-$180,000. Newton's dad confessed that he had shopped his son, but did not receive money from Auburn.
The NCAA conducted an investigation and could find no evidence that Newton's family received money or that Newton himself knew of the pay-for-play scheme. Newton went on to win the Heisman Trophy and will forever have his worthiness questioned.
