Fullbacks have always had a fascination for me.My final word on Gary Jack..if only we had a FB of his caliber today? He had all the skills and a tough resilience. Loved watching his kick returns, at top speed.
I'd say, even as the style of their roles has changed over decades, the fullback remained crucial to the teams they played for.
I just loved their strengths.
Too hard to really say one more than another, simply because each brought something special.
