I say good coach because he apparently does this with inferior talent. But the Bronco Haters claim Bronco just can't develop talent - which is disproven by Ziggy who owes almost all of his development to Bronco. But they will counter that Ziggy was a pure talent that Bronco held back - which is ridiculous if you know anything about sports.
My point? There is always an excuse to blame Bronco apparently.
