It’s commonplace to slap pro athletes with the charge of greed. People such as Ruben Brown and his pursuit of a $4- to $6-million-a-year contract. People such as Bruce Smith and his declination of a Bills pay cut to pursuit a rich five-year, $25-million contract with the Redskins. Still, pro athletes – particularly football players – are underpaid compared to what other entertainers are making in the industry.
