Foote wasn't ever a big point producer, but he was elite defensively and the perfect defensemen for his era. Vlasic and Foote are not similar in size, but in being in the elite defensive category and fitting their role (in their era) perfectly... they are similar. If you think Vlasic is a #1, then Foote was. If you don't, then I can see why a person doesn't think Foote was.
IMO Foote's biggest issue offensively was more around that once he started to get some age, he just couldn't stay healthy. Even when he played, he was far from 100%
Disagree slightly. If anything he had more trouble staying healthy when he was really young and played a super-rough physical game. He changed things up after double shoulder surgery and became a more complete defenseman.
His biggest issues offensively were simply that he didn't have the instincts nor the real ability. He wasn't a slick passer who could get pucks to forwards through traffic and wasn't gifted with a great shot. His ability to move the puck up-ice remains a bit underrated though. But I really don't recall him being a guy who jumped into the play much.
