The primary argument for Tanner taking over the #1 spot if Taysom stays or not is that Taysom is injury-prone. If that's a valid argument, why is the fact that Tanner was also injured discounted? In Tanner's one year sample of games, he played hurt in about half of them. Is it that he was able to still play even though he was hurt that people think he's invincible where Taysom is Mr. Glass, doomed to a season-ending injury within 4 games?
Katbacker obviously isn't saying this is a reasonable argument against Tanner (and neither am I), but it sure seems like the same argument made against Taysom.
