Well if I recall Billy O didn't meet or speak to Brock before they signed him right? I always felt this was rather Odd. Even sports analysts mentioned how strange this was at the time. If true then it definitely makes sense now. Bob McNair, Rick Smith and his booty buddy Doncos in Denver. I think O'Brian wanted to show the players on the team that he had the least amount of influence of the 3 stooges inking this Brock deal in case it imploded
It's odd but that's the rule. I don't think they're allowed to directly contact a player, much less bring them in to tryout or interview, until the free agency signing period starts. They're only allowed to contact a player's agent 2 days before the signing period starts.
