Yet I’d likewise suspect that Porter-related pressure on Nuggets executives is not what it appears from the outside because Porter’s biggest fan, league sources say, is Stan Kroenke. Owner and player share Missouri as an alma mater and Kroenke — although he relinquished day-to-day governance of the Nuggets to son Josh to adhere to the NFL’s rules about cross-ownership of various sports franchises — is said to have been Porter’s No. 1 backer in the organization since the day Denver drafted him.
