The NFLPA has released its annual team report card, which is a direct reflection upon the ownership of the franchise. It’s a good barometer for how the players feel the franchise grades out in various categories.
Much of these grades come from the age and advancement of team facilities, so the Denver Broncos with the third oldest stadium in the AFC West would need to have a lot more upgrades done to keep pace with brand new facilities enjoyed by the Las Vegas Raiders and Los Angeles Chargers.
Overall, I think they have kept pace fairly well.
