For my two cents, which is worth two cents, I say just go ahead and sign and forget the other meetings. If you and your wife want to be here then sign!!
With Alonso here and his deal officially announced on Saturday we'll probably have the Machado deal done on Sunday! Then Hahn can work on the Harper deal next week.
I'd consider something like you propose. On the MLB program this afternoon I heard someone suggest that Harper might not sign until mid January. What if we don't get him. What does that do to other signings we may lose? I'm just saying if the Sox go in another direction it won't break my heart.
