1 Mitral stenosis (the narrowing of the mitral valve) causes enlargement of the left atrium and that promotes extrasystole;  Myocarditis (myocardium inflammation). If this condition is treated incorrectly or it is not treated at all, then various rhythm disturbances as well as extrasystole may occur as complications.
The six-year, $61 million contract that Oakland Raiders quarterback JaMarcus Russell received as the No. 1 pick overall last year contained $29 million in guarantees â a 76.7% increase from the $16.4 million in guaranteed money Cincinnati Bengals quarterback Carson Palmer received as the top pick in 2003.
Not all NFL players make as much money as the sport's stars, of course. Last year, the average salary in the league was just over $2 million. The average salary for the top 100 players in the NFL is $11.6 million, 29 percent less than that of the top MLB players and 13 percent less than NBA's best. The lowest-paid players in the NFL made a relatively meager $420,000, reports Forbes. That's less than one percent of the $44 million NFL President Roger Goodell takes home, and reflects a salary cap system that has teams investing the bulk of their money into their top few players.
