No one who ever encountered Jerry Collins on the rugby field would forget the experience.
Collins played with no concern for his safety and pound for pound, hit harder than anyone.
Who could forget when he thundered into Colin Charvis in 2003 and the Welsh hard man was unconscious before he even hit the deck? Or the way Collins and the Springboks' equally tough Schalk Burger would knock lumps out of each other in tests.
Collins never asked for any quarter, never expected it and never gave it. That's how he won global respect.
