Not when you're the Yankees or Red Sox, they can easily afford to have a lights out closer. Both teams are in business to win titles, not just hope to contend for a playoff berth and a great closer can be very important in that goal. As for his age, did you see his numbers last year? 1.80 ERA .83 WHIP .183 BAA The guy is amazing. He's 40 and pitching as well as he ever has. You are right. Closers are very, very important. That's why the Twins fell completely apart when Joe Nathan got hurt last year. They had no chance to make the playoffs let alone win their division. How many times will a team have to take a good reliever and make him into a serviceable closer before people stop overvaluing the position?I agree with you in a general sense for a sizable percentage of teams out there who often have tight budgets and thus an expensive closer isn't worth the amount of the budget that they eat up. Teams like the Yankees and Red Sox though are different animals from say the Brewers or Indians. The Yankees have such vast revenues that they have no reason to take chances on hoping that a cheap reliever ends up being able to be a reliable closer. If the Yanks went that route and it backfired, thus losing a few extra regular season games via more blown saves that cost them a playoff berth by a game or two or that reliever blew some saves in the playoffs/World Series, they'll look and feel stupid given their insane revenues easily allows for the luxury of a proven reliable closer. Rivera has been a highly paid closer for awhile now and certainly has earned his money for the franchise regardless if closers as a whole are overpaid. Now if the Pirates, Brewers, Indians, Rockies, Rays, or a number of other much smaller revenue teams tie up a significant chunk of their budget on a closer, that i'd agree will often end up being a poor use of funds.
