If they're going to match any offer I would call their bluff and offer him a large contract just to get them cap-strapped for the future. Then again, I'm not an NBA GM and many would hate me for those tactics.
To offer him a large contract, you would have to renounce all free agents and the MLE. It's stupid to do that if you expect Utah to match.
One of the biggest examples of a team making stupid moves to sign a restricted free agent to an offer sheet was Golden State using its amnesty on Charlie Bell (instead of Andris Biedrins), rescinding its qualifying offer on Reggie Williams, and waiving the unguaranteed contract of Jeremy Lin to sign DeAndre Jordan to an offer sheet that the Clippers were easily willing to match.
