Crisp ceiling as a .280 hitter? Except those years where he hit .300 right? Forgot about that. Go on a hunt and find what his BA was from July 1 to the end of the season.
I don't know if Ellsbury projects to be Sizemore or Beltran good either... I've certainly not heard any of those comps. I've heard people say his swing has a little Beltran in it, but his frame certainly doesn't.
The Sox can't let this deal fall apart over the inclusion of Ellsbury. We would be selling insanely high. He is going to be a good player, for sure, but right now he is considered almost elite - if not he is considered elite - because of the series. He set the world on fire when he got called up, but his production over the next few years will probably not be so far off vs. Crisps production that it is worth it to keep Ellsbury over Crisp in a deal for probably the most dominant pitcher in the game right now.
Sure, in a vaacum I would rather have Ellsbury. Easily. Thing is, in baseball, decisions are never made in a vaacum. I would rather have Santana and Crisp than Ellsbury.
