[blindside]

i don't think it will happen simply because there is too much money at stake now where if one is a star in one sport.. he will be heavily influenced to be committed to just one... ala smarjidakzljalsdfj... or however you spell his name...

but by pure numbers there will be athletes who will have the capability to do both so if money wasn't a factor and the team did not mind.. then yes i would say it is very likely to happen again...
