He never seems to come across well, Groves is right about him inflating DeGale's ego as much as possible. Not that it'll help Groves much, as DeGale's a class above IMO, but surrounding himself with a team that just blows smoke up his arse could be his downfall on the world stage.
Hes a class A wanker. I made a thread on him a few months back. When DeGale losses against Groves it wont be DeGales fault, it will be Jim MacDonalds. Once DeGale gets beat, Jim is getting sacked.
He's a nob. Jumping up and down like a little girl when DeGale mentioned the bet. He's not a good trainer, he's a yes man for Degale sitting there telling him how good he actually is. he'll get you fit but in terms of techniques, shots, defence etc etc he's wank. DeGale just happens to have that in him
