I was a big markov fan, but since you are using norris trophies as a metric in your post, I will say Weber was alot closer than markov.
He lost a couple close norris races, and one of them was closest race of all time where he barely got beat out by lidstrom.
He was a lock to play on the best on best Canadian teams among guys like Keith and doughty as well.
I don't use overrated and underrated terms because everyone is basing the benchmark on their own perceptions, but it should not be a controversial take to say thay he was an excellent dman in his era.
