His only chance? Really? Do you remember last weekend when he won using something completely different? Grappling is his best chance, not his only one. Now Weidman's striking has got Silva's respect I expect his likelihood of landing takedowns to go up as well, not down.
Silva will use vaguely the same tactics, he'll shake his head, clap his hands, stamp his feet and call him on and try as hard as possible to disengage from any grappling at all. Obviously I would never count him out, that would be silly. He's Anderson **** Silva for feck's sake. I definitely wouldn't have him as favourite though.
Last time I was 55:45 in favour of Weidman, now that I know he has the potential to cause problems on the feet as well I'd say I was more like 65:35.
