But Garrard won't be around long enough to find out.
"Having to call it quits," Garrard wrote in a text message to NFL.com's Adam Schein. "My knee is not holding up. Continuing to swell after practices."
Garrard started training camp in Miami last season atop the Dolphins' depth chart, but a knee surgery wound up ending his season before it started. Garrard hasn't taken a snap in the NFL since 2010. We doubt he ever will again.
