Puma believes the contract offered to Wright translates to significantly less dollars in the short term, although its unclear as to how much money would be deferred.
This is actually a pretty big sticking point, since the Time Value of Money can significantly reduce how much cash ultimately ends up in Wright's bank account.
The way I understand this, similar to Johan Santana and other big-name free agents of the past, the Mets likely deferred money to be paid to Wright long after his deal expires. For instance, the present-day value of Santana's contract (when it was signed) was actually said to be $121 million, as opposed to the $136 million that was announced. Why? According to reports, $5 million of his salary was deferred annually at 1.25% compounded interest (payable starting seven years after the season in which the salary was earned). It's a nice, stable retirement plan, I suppose. But, it's also less cash-in-hand now, which may have gotten more than a 5% return had it been better invested.
It seems to be a recurring tactic with this Ownership. And, while Santana and others seemed to have no problem with it, clearly Wright does. That's his prerogative, especially if he believes he'd do a better job investing than the Mets. On the other hand, the Mets no doubt prefer to defer the payments so they have more capital on hand in the short-term (either to pay down debt or add new players to the roster).
Frankly, this is all a little technical for me. I simply want to see Wright sign a deal and I want the Mets to know how best to move forward on rebuilding the roster this winter. But, I get it. It's David's life and personal finances, and so I'd be a stickler too; and probably equally angry if it was all made public, as well.
