It's such an exciting fight. In experience, size, power, jab and footwork Groves is obviously ahead, but can he cope with Junior's youth, speed and aggression?
If Groves can stick to a plan and not get drawn into exchanging with Junior I think he wins on points, as long as his slightly suspect conditioning holds up. If he does manage to win, then Junior really is on the verge of becoming the special fighter him and his dad have been assuring us he is.
Whoever wins this one, Mundo takes care of them in the final imo.
Edit- think we're singing from the same sheet @SARJ!
