Guys on the franchise tag fail to participate in voluntary activities probably at least 50 percent of the time. It's a business decision. No player wants to play on the franchise tag and risk taking an injury that permanently damages his ability to earn money for the remainder of his career. Doing this is a way for a player to step up and say you can walk away from our long term contract negotiations and compel me to play for you for a year under the franchise tag, because the CBA grants you that ability, but the CBA also grants me the ability to make that an unpleasant experience for you to some extent. Actions have consequences. The Dolphins walked away from long term contract negotiations and slapped the franchise tag on Starks. That action has consequences, no matter how selfish fans want to be about it.
