>>>"Is it really necessary for anyone to have that information before posting their opinion on Alderson's inactivity?"<<<
In fairness, yes I do. I do if someone is going accuse the GM of being asleep by not acquiring a specific player like this.
I think the person should at least be able to produce some shred of factual, or at least rumored evidence, that the GM just sat on his hands and never ever contacted the agent, or never made a credible attempt to make a deal. And also, that the player was even open to playing here.
Sometimes people just assume that because a player is "available", that all they have to do is want him, and he's ours. Well, it doesn't work that way that I know of. Not every player is available to us, and we don't always know the reason(s) why.
For all we know Sandy had several discussions with the agent, but they asked for a ton more money from the Mets because they are a bad team.
For all we know this player told his agent that New York was one of several teams he didn't want to play for at all - not unless he had no other better offers.
For all we know he had something in his medical records or off the field background that made Mets question trying to seriously acquire him.
I don't know what did or didn't take place, I just think it's unfair to accuse the guy of being asleep and not doing anything, when we have no clue as to what he actually did or didn't do with regard to this player.
