Sorry I will take the word of someone who works for the organization over yours. Just threatening to drag out the process to piss off the Suns ownership is 100% burning a bridge, especially when it is a brand new owner.
I can't recall a team ever matching before the end of the allotted time, but would be interested in hearing examples. Besides it gives the matching team time to pursue other signings while they still only have the QO on their books instead of the full contract.
I have no doubt the Suns would do the same if the situations were reversed, it's just sound business.
