Well, there is no doubt that Mike worked his socks off at times when he played for the Devils before, was one of the Devils' regular point scorers...and fought his way back to fitness from quite a serious injury which is very admirable.
Whatever the previous issue before last season which saw his release from the Devils, Prps appears still to be respected and liked by players and the organisation...otherwise he wouldn't be training with them! Although not personally one of my favourites, it wouldn't suprise me if he is sought after by clubs in the UK.
As far as the Devils are concerned - he knows them well, they know him. I suppose the question is whether he could be a good fit now and whether he is needed.
