Sounds like the pistons are following the strategy the suns are usin with Bledsoe. Basically, don't overpay unless you have to, don't make an offer, just threaten to match any offers other teams make. It seems to have worked at least in driving down potential suitors for these guys.
And this is exactly why I hope Monroe, and Bledsoe too, take the Qualifying Offer, play out the season, and then leave their respective teams with nothing, as unrestricted free agents, the following summer.
This is something I've wanted to see players do for some time now. The team's have too much power over RFA's, and playing for the QO is a way for the player's to take back a bit of the power. Many RFA's get low-balled in contract negotiation's for this exact reason.
The purpose of the QO has always been, partly, to be a sort of "threat" to teams that refuse to make good faith contract offers to RFA's. The problem is, because almost no player ever goes that route, it is nothing more than a hollow threat teams pay no attention to.
