Love that site. Too bad it requires a subscription/limits access.

Welmer's worked 44 games as of yesterday, 12/29/2007. In December, he had off the 6th, 7th, 24th, 25th, and 26th. That's 24 games in 29 days in December.
Bwtween his season start on November 9 and today, he's had a total of 44 games in 51 days. Wow. Say what you want about his post-season assignments, he sure is wanted by enough people to keep him working day in and day out.
