Your offense is very strong and yes, an infield backup would help, IMO. I'm just not sure who that could be. Without a look at your wire, I doubt anyone would be better than any of your "worst" players.
Your pitching is amazing, so I am tempted to say sit and wait for the next big thing, but in a 10 team that depends on the wire. I don't think CJ Wilson is legit, personally... I don't have much to back that up with, but I never saw him as anything more than a #2-#3 starter.
Having Storen gives you good saves leverage going forward, so other than Hellickson and Worley, your pitching is surefire solid.viewtopic.php?f=29&t=447385#p3527957
