Andrew Marchand of ESPN 1050 reports that the Mets are willing to give Perez a contract for four years, likely worth $10 million per.
That is way too expensive. I wouldn't mind Perez back in orange and blue, but for that much, over that long of a contract just isn't worth it. He's honestly not that great of a pitcher to command that much money.
But thanks to an over-eager pitching market, other pitchers got more than they deserved, so Perez will as well. (Thanks, Atlanta!)
The Mets are better off signing Perez for two-years and giving him more per season. I don't think Perez is a reliable enough pitcher to sign for that length of time.
Update: I just wrote this in a reply to a comment...
I don't think there are any other teams! If there were, Boras would be parading them around like circus elephants trying to drive up Perez's price. But if that's not happening, I'm pretty sure no other team if willing to offer this much money to him -- and rightly so.
