There are rules for this. Players NEED an off season. If they don't have rules for this then THERE ARE coaches out there who WILL work their players 12 months a year. NFL has had major problems controlling this over the years. Jerry Glanville was notorious for having 'voluntary' spring camps, but of course if you didn't volunteer, you went into the doghouse or were cut.
The fine should be bigger in my opinion. I know it was only 3 days or something, a month before TC, but it's a huge slippery slope. Off season means off season. Players need it. Just the fact that someone in this thread has already mentioned, 5 grand? Small price to pay. He's right. I'm sure Taman and Hopson knew they'd get a 5k wrist slap and did it anyways. That tells me that the fine should be BIGGER, like 2k per player per day, so 3 vets for 3 days = 2k x 9 or 18k. 10 vets for 2 days= 2k x 20 or 40k. THAT will make them think twice.
And they should be payable to the players association. That way, the possible breach of CBA would make the league take it more seriously.
However I AM glad to see the league act at all. I have to give kudos for that.
