Is the Mets CF Beltran a cosmic disappointment?

When he came up with the Royals they said he had the switch hitting power of Mickey Mantle, the legs of Lou Brock, the throwing arm of Roberto Clemente, the range of Willie Mays, the first step of Jackie Robinson, the grace of Joe Dimaggio, & the batting eye of Ted Williams. He has made me very mad as i have followed him since he was a rookie & he has not lived up to being all those guys all rolled into one. Would you say he has been a big disappointment?
