I don't think it is close. Holland is the better pitcher but broxton will close until he blows a few saves or is traded to whatever contender loses a closer or setup man. (Reds?)
This sounds reasonable to me - Brox is a very marketable guy for the Royals both to their fans and if he doesn't completely suck, a contending team (assuming the Royals don't pull one out of the hat this year, who knows?).
300 lbs of Jonny Brox running out in the 9th with ACDC or Guns N Roses (or whatever) blasting is good theater...
