So you are declaring the Mario signing as wrong after 4 games and that is a sign of being open minded? I'd call it reactionary. Yawn.
Based on the evidence Nix had at the time, trying to sign Mario WAS the right thing to do. It may or may not work out, it is too soon to tell. Mario has certainly contributed next to nothing so far to be sure. But a bad signing stance this early, to me anyway, is a fan knee jerk response. Not a sign of being open minded. YMMV.
