Yes - it's about Crisp only.
I don't think the other teams see great value with Coco's total package - and they are not calling Theo up for a trade for Coco. I think that Coco's balanced package would have been nice in a team like 2003-2005 Red Sox. 2007 team was actually light on offence and we did get by because the Yankees were slacking in the first half and because of our pitching but we should not push our luck. I remember lot of games where the piching was light's out but the offence really let us down( Dice-k suffered most if my memory serves me right). And - we do have the same questions with 2008 team as basically they are the same team( Manny's being Manny, Ortiz's injury, Lowell's effectiveness, Drew/Lugo's/Youk's consistency, Varitek's ineffectiveness etc.). That's why Ellsbury made a difference last year - because he was a spraking plug in the tepid offence ( the bottom part of the line-up before Jacoby was downright aweful). I would argue that he might have helped some other players like Youk and Lugo to get their form back by taking pressure off and he always kept pressure on opposing pitcher and defense. Now - is he replacable ? - absolutely specially for someone like Sanatana. But being already light in offence and seeing what I saw last year - I think we do need an upgrade to make the play-offs. That's why - for this team - I do not think Coco's total package is enough for this team to repeat.
Hopefully I have made my opinion clear. Now - if we trade Jacoby we might have to settle for Coco for next year at least for the lack of better alternatives. But - I will not be exactly happy about that.
