Deion Sanders -- There Will NEVER Be Another Pro 2-Sport Athlete

There will never be another athlete like Bo Jackson and Deion Sanders .. so says Prime Time himself who claims the days of the professional 2-sport athlete ARE OVER.

Deion called in to "TMZ Sports" this week and told us why Seattle Seahawks QB Russell Wilson (who was just drafted by the Texas Rangers) should seriously consider pursuing a career in baseball.

But during the convo, Deion made it clear, Russell will have to choose a sport -- he can't have both.

In fact, Sanders says the way athletes are bred down at the high school level prevents them from getting the proper exposure to multiple sports. Sanders points the finger at "selfish" coaches.
