The Wall Street Journal has a story on the company Player Protect that provides security and transportation services for professional athletes when they are attending social events.
Jets safety James Ihedigbo said ceding control has never been an issue. The Jets signed with Player Protect this past September, and Ihedigbo said he has used the service both as part of a large group of teammates going out after a game, and on his own. He has never been in a situation where his assigned officer indicated he was unsafe, but if he was, he said, "I wouldn't even hesitate to listen. It's what they're there for. Their ears can pick up things mine can't."
The goal of the company is to not only keep the player physically safe but also for the agents to keep the player informed of anything that might come up during the event which could put him in harm.
