As I remember him, Ruettgers was a little better than that, certainly not Pro Football HOF material but I read somewhere he was ‘steady and reliable’ and that’s how I remember him. When healthy he was a good enough LT to win it all with IMO. Speaking of being healthy (I had to look this up of course) Ruettgers missed 10 games from ’86 through ’90 and he only missed one game from ’92 through ’95. So while his career was interrupted by injury, missing 11 games over 9 seasons is fairly “available”.
I’ve posted this before but whenever I hear/read the name Bruce Wilkerson I think of this story. Ruettgers was at the end of his career in ’96 season and began the season on the PUP list (he was active for 4 games and retired after that season). Anticipating this, Wolf reached in the first round of the ’96 draft for John Michels who wasn't the answer at LT that season or thereafter. So Wolf signed veteran Bruce Wilkerson before the opener for depth. As I remember it, toward the end of that regular season a couple of vets on the team lobbied for Wilkerson to step in at LT. He started the last regular season game and for the rest of that great playoff run. The difference was night and day and at the time Wilkerson was just one season away from retiring from the game.
In Holmgren’s offense one of the O-line adjustment calls the OTs had to make before the snap was "Cow!" Not a problem except Bruce had a stuttering problem. In a game prior to that Super Bowl after struggling with the "C" in cow, he finally shouted, "Moooo!" While everyone knew what he meant, half of them were laughing too hard for the play to be successful.
