It was leadership, yes, but it was more than that. Irvin ran very precise routes, put in full effort at all times, had a burning desire to win and succeed, and had an excellent attitude.
I would take Mike any day. Mike had the heart of a lion, and a winner.
Mike did at times make me say "Wow that was stupid." However, the difference between Mike and Dez was leadership. Mike was held accountable for being stupid from the HC, the QB, and rest of his teammates. We did see Romo talking too Dez on the sideline after he ran the wrong route, but I wanted and need to see JG bite off into his butt.
Dez can't separate from the CB. Irvin caught 12 passes against the best cover corner in the NFL at the time, and one of the best of all time, in the playoffs on the big stage. Dez was caught lolligagging on nat'l TV vs the Gnats last year w/ the playoffs on the line.
Seriously, it's not even close. At present, it's getting so bad I'm starting to agree w/ the guys who say we should take his number away.
