To be honest, I'm not even going to try to keep up with Thomas this season. I think he's had at least 4 or 5 masks already, and lots of pads too. I don't have the time to keep up.
Thomas was traded to Dallas in March.
Both of these photos are listed as March 20, 2014, so I don't even know which mask he's wearing.
