NFL coaches are flummoxed, something they don't like to be a week into training camp. What to do about Twitter? The league encourages players to join the social media site (about 300 have accounts), and commissioner Roger Goodell even filed dispatches from the NFL draft (nflcommish: "are u ready for some draft picks?"). But among control-freak coaches, there's a wide spectrum of tweet tolerance.

• The Jets are so pro-Twitter that they've hired a "social networking intern" to help players post updates and photos. "I think our fans find it interesting that [kicker] Jay Feely's eight-year-old daughter finds it weird he takes naps," a Jets VP said on CNBC.

• Last week Chargers coach Norv Turner pulled Antonio Cromartie (left) out of a team meeting to inform the cornerback that he had been fined $2,500 for the following tweet: "Man we have 2 have the most nasty food of any team. Damn can we upgrade 4 str8 years the same ish maybe that's y we can't we the SB we need."

• Any Packer caught Twittering during team functions will be fined $1,701 for the transgression. Running back Ryan Grant (9,131 followers) has already adjusted his schedule. He told his tweeps, "Expect tweets in the morning before we go to work, possibly around lunch time and at night once we done..i dont want that heavy fine lol."

• Believe it or not, Bill Parcells is not sweet on the tweet. The Dolphins' executive VP bans fans and reporters from tweeting, blogging or texting from training camp. Coach Tony Sparano has the same rule for players. "I was thinking about getting an account," nosetackle Jason Ferguson told The New York Times, "until I got the information."

• Josh McDaniels is the anti-Parcells. Joked the 33-year-old Broncos coach, "I don't really have a Twitter policy. I don't know what it means; I don't know what it is. I don't know MyFace, Spacebook, Facebook stuff. I don't know what that is either."
