Cinci had one hell of a year, but I don't think they can win 90 again. Right now I'd put my eggs in St. Louis's basket for 88-90 wins, with the real fight being between Cinci and Milwaukee for 2nd place and possibly the wild card. A big (contract) year from Prince plus the addition of Marcum and Greinke could do the trick.
Will Weeks stay healthy? doubt it
Will McGehee continue slightly above avg production? doubt it
Will Braun rebound from great year and have amazing year? probably
Will Fielder perform during contract year? yes
Will Hart repeat? no
The rest of the order is absolutely terrible!
Their defence wasn't very good last year and probably won't improve.
Sure they're rotation is good, but their bullpen isn't much of anything either.
