Chiefs quarterback Matt Cassel has taken a beating at times this season, but he remains confident that he has an advantage when it comes to avoiding a concussion, his mouthguard. It was developed by Gerald Maher, the team dentist for the New England Patriots. Cassel spent the first four seasons in the NFL with New England before being traded to the Chiefs earlier this year and the Patriots are believed to have had the fewest concussions of any NFL team last season. "Dr. Maher's work with the Patriots is pretty well documented," Cassel said. "The guys in that locker room trust the protection that his mouthguards provide, and once I tried it, I won't wear anything else. As quarterback, you want a mouthguard that not only gives a high level of protection, but is also comfortable and still allows you to speak audibly. Dr. Maher's mouthguard gets an 'A+' in all of those respects." Source: Kansas City Star
Probably just one of the double sided Boxing mouthguards that I've heard so much about, craps sposed to really help.
