Coming off a weekend solely dedicated to boxing 'Talking Tough' took the approach of discussing a lot of topics concerning boxing in MMA.After Manny Pacquiao's less that stellar showing against Shane Mosley and the previous week's less than stellar performance by GSP at UFC 129 we looked at both outings and tried to draw similarities from the two and why fans gave GSP a mouthful and not so much to Pacman.Also on the table, we discussed the potential Jeff Lacy vs Nick Diaz bout that seems all but set in stone at this point. Does Nick have a better shot than people are giving him credit for? Tune in to get our opinion.
