Was Derek Jeter a great shortstop? Sure. But Rivera was the greatest closer of all time - and Derek Jeter is not the greatest shortstop of all time. I truly think Rivera could have pitched effectively for a few more years (maybe forever - that man is probably an android), whereas Jeter stopped being an effective defensive shortstop some time ago.
I also think Jeter's level of respectability has been inflated by playing next to the baseball pariah Alex Rodriguez for so many years. Jeter may have kept himself out of most major scandals (though not all), but he's no Saint Mo. I'm sure some teams will send the Captain off with a parting gift of some sort, but if he's looking for the same sort of emotional sendoff all over the league, he's got another thing coming.
