The Boston Celtics made a big move in advance of the trade deadline recently.

But it wasn't one of the normal Danny Ainge monster signings. It was a little more under the radar, but still very significant to the franchise going forward.

The Celtics picked up Greg Monroe off waivers for one year and $5 million dollars after he successfully reached a buyout agreement with the Phoenix Suns. The move adds to their frontcourt depth with a player who is still young and is very talented.

But the Celtics don't appear to make the signing official until after the trade deadline, per Adam Himmelsbach of the Boston Globe.

This is actually a great move by the Celtics. With just a few days before the deadline, the Celtics could still make a deal. There's talk that Marcus Smart may get moved, and that's just one possibility for the Celtics.

So if the Celtics want to keep all their options open, it would make sense that they don't commit any salary until they for sure cannot do anything else to their roster via trade. That does not mean, however, that they don't Monroe. They wouldn't have grabbed him off the waiver wire if that were the case.

But so long as the Celtics have the opportunity to maximize their financial flexibility, they should take full advantage of it. Monroe's contract is that expensive, and the organization can afford to wait just a few more days to sign Monroe.

It will give team the opportunity to make a good trade and then bring in Monroe, giving the Celtics a chance to get the perfect roster for this year's playoff run.
