"Our policy here is that our information is our information, and it should stay in-house," Sparano said. "Something they think is innocent can really hurt an individual, can really hurt team chemistry, and maybe can lead to somewhere down the road a loss of a game. I believe that. I'm one of those guys that will try to take that variable out of the way if you can.
"But it doesn't look to me like something that can completely be controlled."
The Dolphins will try. They require the media to shut off all electronic gear — computers, cellphones, cameras — about 25 minutes into practice, when team drills begin. The Dolphins are also policing fans, a daunting challenge for a team that drew more than 3,100 spectators to the opening workout last week.
"I would acknowledge that enforcing the restrictions can be difficult," said Harvey Greene, Dolphins senior vice president for media relations. "We're not looking over everybody's shoulder, but we do have a concern about information flow."
The Professional Football Writers of America has complained about the media restrictions at practices open to the public. The Jaguars and Vikings initially prohibited tweeting by reporters but lifted their bans following complaints.
"It would be a shame for a beat writer to get beaten on a story by a 12-year-old in the stands who is allowed to blog," said Charean Williams, president of the PFWA. "I appreciate the teams that have reversed their policies, and I think the league will listen to us and we'll get this changed for 2010."
Some teams are coming to terms with the new technology. The Eagles have an air-conditioned trailer at camp for bloggers. Jaguars coach Jack Del Rio sends text messages to reporters.
Browns coach Eric Mangini laughed when asked about concerns that information regarding an injury might leak via a tweet.
"There are all different avenues to communicate," Mangini said, "and I think they're great ways to communicate."
Even at Dolphins camp, the 21st century is making inroads. On Wednesday, Sparano said he just learned how to text.
