It's just one of many myths

Perpetuated by the internet/messageboards/media types.

People have that impression of Fisher because of what his O was when he was bring McNair along and had Eddie Goerge and what he did when he has crap at QB with Vince Young.

So people assume that's what he "is" despite several years of not being that at all.

But you cannot change peoples minds even with facts, so why bother.
