I don't think, at this point, Reed Johnson is an improvement over someone who looks to be next in the Holliday, Atkins, and Hawpe line of Rockies farm system products. If he was a starter, I think he'd be rookie of the year in the NL. I'm not sure how he is with the glove, though, either. In the games I've seen him play defense, twelve of them were spelling Garrett Atkins early last season at 3B, and then playing first base for a game this year. I think Hawpe and maybe Atkins' contract is up after this year... I hope the Monforts aren't intending to be cheap and that they actually bring them back!
I don't think offense is going to be the problem. Though they've struggled to this point, they'll get their act together offensively. If they're going to look outside of the organization for help, I'd prefer it be to improve the shoddy bullpen.
