Without wishing to detract from his legacy, I do think he did have some benefit of the era he played rugby in, certainly early on his career. Literally a man among boys:
What chance does does a 5'8" 85 Kg Tony Underwood have of stopping that beast of a man (6'5" 119Kg!), even when he's stumbling vs sprinting!
That said, I do think he was an out of this world athletic/rugby talent. So sad to lose him prematurely.
I'd have loved to see if could have had a shot in the NFL. He compared very well, to say, Megatron physically. Roughly same height
