I don't think that rotation is good enough to compete with the Cubs. Honestly, I think it would put us around 86 wins, and the exact same position we were in last year. Cobb doesn't move the needle at all IMO. That rotation lacks firepower at the top. Should Lester regain form, the Cubs' top 3 pitchers would be better than our best. Only adding Cobb to the rotation would be a disappointment in my book. I would like him as the 2nd addition to the rotation. Cobb would be the 2nd addition (Chacin was the 1st). We had a top ten rotation last year. We shouldn't be using resources to get 3 new Starting Pitchers when we had a top ten rotation. One to fill in for the injured Neslon - agreed. A second to upgrade the peralta/garza/suter/guerra spot - agreed if Hader is bullpen only (seems like it). A third to push out promising rookie (Woodruff), block promissing minor leaguer (Burnes) and to relegate another starter to the bullpen (Chacin) when Nelson comes back - waste of resources. At a certain point, there is significant diminishing returns. We also have significant injury depth in the 6th/7th/8th starter (someone who can be in the bullpen or in AAA) in Suter, Guerra, Wilkerson, Burnes. I don't believe Anderson will replicate last season. Good pitcher with a 3.75 ERA sounds about right. No Nelson and who knows how he is when he returns. Right now I'd rank our rotation around 15th in the league. Middle of the pack. Cobb would probably push it to maybe 12th or 13th. If we're trying to win 86 games again, I think we'd be good with some improved OF production (assuming everyone else somewhat replicates last year). If we're trying to win 90 games and compete for the division, I do think we need a TOR type of pitcher or at least a #2 kind of guy.
