Actually.. Not sure that Ronnie is so elusive.. as he is great a breaking tackles. He is NOT an easy guy to tackle. Don't get me wrong. He's got moves. He's definitely juked his share. But, he is more of a power back then an elusive guy. But, that's what makes him dangerous... is that combo. If he could just stay fricken healthy and not get gassed on long runs.. I think he'd be the best in the league (Under those circumstances)
DeMeco Ryans has said that Ronnie is the hardest RB in the NFL to bring down because of his elusiveness at the 2nd level.
You don't notice it much, but after that first wave of defenders, Ronnie is extremely quick.
