I would think that’s the norm. You get a lot of skill position walkons but the big boys in the trenches probably don’t see slogging around in practice with little to no chance of seeing the field as a fun way to pass your afternoons in the fall.
What better way to prove it! I bet pigs of your time at tryouts would do wonders for your TNet pulse, though probably not so much for your actual one. May not want to share your TNet handle with any of the players or staff, though. They may not look to kindly on a #### in Tiger's clothing.
