Two thoughts here:
1. I think we've seen about the worst negative variance we could have in terms of results from this team (looking at RD and the timing of when the pen has crapped the bed in particular plus the poor performance with RISP during cold stretches).
2. I think the goal is to have all those 3-4 WAR players home grown and affordable so they can go out and get the 5-8 WAR guy(s) in FA to put them over the top. As a team operating in Chicago with Wrigley as an asset, I don't think that's an unreasonable approach, it just hasn't come close to fruition at this point.
