I think he may get Murray out of there before the seventh. Groves hits hard and Martin is hardly elusive.
I think Murray showed his level in his lost to Abraham, who was arguably beaten by Paul Smith a year before and lost every round and hardly landed a clean shot against Gilberto Ramirez. I have it from a good source Abraham was decked by Luke Blackledge, which shows how much he has declined.
Would love to say Murray however think a would bet on Groves. This fight could be a *******, hard to say. Groves ko round 8 and above
Groves early, TKO, maybe a bit of a "British stoppage" because I can see Murray going in to his shell. Murray will tuck up, tight defence and try and get past 4-5 rounds and take it late but I think he will be too negative, not open up and Groves will be able to unload without the fear of punches coming back at him and might force the referee to intervene.
