It's not a bad signing. It does show off JimBo's chief strength - bottom fishing.
Nothing to get overly thrilled about either. I think Jimmy Haynes is a fair comparison for him.
Still doesn't make this better than a third place club.
Two quick thoughts: The Reds have a lot of similar pitchers in their starting rotation (righty location guys). They could really use some different looks (e.g. righty power pitcher or southpaw of any stripe).
Also, the preponderence of RHPs puts a lot of pressure on Bruce Chen as a middle man. IMO, Lance Davis should get a long, hard look this spring as another lefty long man.
