Guys can move the line betting on their own team, use that to their advantage. Rose bets, say, 10k on his team like a week straight, then one day bets 5k. People in the know will think something is wrong with his team. Someone's injured, etc. It will get back to Vegas and move the line. Just one example of how easy it would be for a famous bettor to do this when placing bets on something they control the outcome of. The rule's there for a reason. No gambling on baseball by anyone involved with the league. Period.
"...the successful annihilation of organized crime's subculture in America would rock the 'legitimate' world's foundation, which would ultimately force fundamental social changes and redistributions of wealth and power in this country. Meyer Lansky's dream was to bond the two worlds together so that one could not survive without the other." - Dan E. Moldea
