Besides Shark, who else is the longest tenured Cub? With a rotating carousel of 4th OF's/utility players, Rizzo looks to be the de facto leader - but he's got 1 full year in. Um, Castro was called up in 2010. But Castro can't possibly be a team leader... I didn't mention Castro b/c hasn't there been some who question whether or not he fits Theo/Jed's ideal? Jed's traded for Rizzo twice.
