That's too deep for me. But what it comes down to IMHO is how far you're prepared to go to apologize for batting average and where you start making the call that OBP is the number that's important -- and that the important facets of AVG are reflected in OPS, at which Holliday excels (and where Bay is a fair bit closer)
I'll take a guy who doesn't make a lot of outs and hits for great power. As near as I can see, that's either Bay or Holliday, and while Holliday's a little better, both players are going to earn their large paychecks over at least the next 3 years.
If we can sign one of them, whichever one it is, we probably won't regret it. Me I'm a conservative -- I prefer the familiar, especially since Bay has proven he can perform in Boston and Holliday really hasn't. Bay's consistency as a home run hitter is an asset I'm prepared to give up a bit of OPS for. But if Holliday agrees to sign with us while Bay goes elsewhere, I'm certainly not going to complain.
I don't relaly care that much which one we get. What I don't want to see is people getting so fixated on Holliday that a perfectly good Plan A-2 quietly signs somewhere else because we're too busy going after a "better" player that NYY has a leg up on.
We need to be in on both Bay and Holliday right up to the elbows and sign the first one that agrees. The chance of getting neither is the big thing to guard against, not winding up with the lesser player among two great players..
