Apparently the NFLPA was set to file collusion charges against the Broncos and Cowboys if Demaryius Thomas and Dez Bryant weren't signed to contracts before the deadline. Apparently during the Dez Bryant negotiations it was mentioned that the Cowboys had spoken to the Broncos.
Thomas and Bryant both signed contracts just before the deadline, but this is where it gets interesting both of them signed 5 year, 70 million dollar contracts. Bryant has about 1.5 million more in guaranteed money, but otherwise they are basically identical.
So the question is, did the Broncos and Cowboys collude?
