For the record: Carolina never offer CMC, Houston counter offer did, reason why there's a stalemate.
Houston rather ship him to NFC, hence they're stalling on Mia.
Mia knows Panthers are the other only contenders so they're staying pat in their deal(which doesn't include Tua)
If Panthers make a deal it's either Monday or off-season, final offer just sent.
Darnold's poor play gave Houston leverage, if Darnold shows up against ATL, Monday's deal or no deal.
