Vaughn Martin appears to have the size and speed to play inside or outside along the defensive front. With the mandatory roster reductions to 75 beginning today, there are at least 10 NFL teams that will be looking to upgrade at DE and DT.
So we will know very shortly if Martin is or is not wanted. Then there is the lure of the NFL, which pays CFL wage scale for practice squad positions. But Martin is Canadian, so there is a better chance for him to return home.
Practice squads are not for everyone. Chandler Harnish, who was a record-setting QB at Northern Illinois, before spending the past three years with the Colts, Vikings, and Cardinals, just turned down a Seahawk offer to attend preseason camp because there was no guarantee that he could compete for a permanent roster spot.
