It is, but completely necessary. Thank God that retard Hal Steinbrenner allowed the fire sale. Cashman did a good job, and frankly took advantage of an awful talent pool at the trade deadline. Frazier immediately becomes the Yanks' best prospect with some legitimate corner-outfield star potential, a la Ryan Braun. Sheffield is an undersized pitching talent with #3 Starter potential, but a very live arm (95mph). Torres from the Cubs is an immensely safe pick up & as close to a "no doubt" prospect at short stop. Guy will probably never be a star, but is a Rafael Furcal kind of player, and you'll certainly take that from prospects. All things considered, the Yankees have a loaded farm system, with some fairly safe prospects, albeit it's pretty safe to say none of these guys are Mike Trout.
The Tate pick up on the other hand is a great lottery ticket grab. Tate has dramatically fallen off since entering pro-ball, but he also had a nagging hamstring issue and at one time sported ace-like potential. Not a bad grab for Beltran (who I think was a phenomenal pick up for the Rangers), but absolutely could be a foreseeable bust.
Ps. Blake Rutherford (Yankees first round pick this year) has been absolutely murdering pro-ball with a 1.200+ OPS. Already ranked a Top 50 prospect, he could be the potential superstar out of that system. Just turned 19, and was consistently ranked a Top 5 prospect out of the draft, but fell due to signability issues/prospect fatigue. Legitimate 5-tool talent, hope the Yanks do not cut ties with him in any trades.
