Everyone knows the big names.
Justin Verlander, Miguel Cabrera and Prince Fielder will all need to have their typical dominant seasons for the Tigers to succeed in 2012.
But when you look at championship teams closely, there are always lesser known role players that step up in key spots to put their team over the top.
Guys like Scott Brosius for the '98 New York Yankees, Billy Hatcher for the '90 Cincinnati Reds, Scott Spiezio for the '02 Anaheim Angels and David Freese for the '11 St. Louis Cardinals all came out of relative obscurity to have decent seasons and stellar postseasons leading to championships.
I believe these five players will be the X-factors that will go a long way towards delivering a World Series to Motown for the first time since the mid '80s.
