Huston Street

Over at Metsblog there is a post claiming that Omar offered Heilman straight up to Colorado for Huston Street. Colorado countered by asking for Feliciano as well, which Omar balked at, furthering my suspicion that he would have been a much better GM in the deadball era (you know, before bullpens were important).

Anyway, some of the folks on the comments thread over there have been talking about Street's very bad save rate (~75% for his career) and saying they don't want him. Others are saying that his numbers have been declining and/or fluky, and they don't want him. I for the life of me can't figure this out, and also can't figure out why Oakland and Colorado seem so eager to dump him. Take a look at the following numbers (sorry they aren't formatted better, I'm slightly computertarded):

WHIP:
05: 1.009
06: 1.090
07: 0.940
08: 1.214

K/9:
05: 8.27
06: 8.53
07: 11.34
08: 8.87

K/BB:
05: 2.77
06: 5.15
07: 5.25
08: 2.56

ERA:
05: 1.72
06: 3.31
07: 2.88
08: 3.73

His first 3 seasons were fantastic, this past season was merely good. He still would have been the best pitcher in our bullpen by a wide margin once Wagner went down. And his '06 and '07 seasons rivaled Wagner: he was better in K/BB and WHIP, but worse in K/9 and ERA. I can't see any reason not to trade Heilman and Feliciano for Street (heck, I'd even throw in some collectible Shea Toilets).  I know Street's like 14 years younger than the age-range Omar normally looks for, but if that really is all the Rockies are asking for, I think you have to make that deal. What do you all think?
