Peters, party piece, was to appear, from no where, into the box, bit like 'an over load' in todays money, whilst putting a lot of leg work for 90% of the game. Very effective, played with his brain, but no great ball player.
Bruce on the other hand, was a bustling, rough, ball at any cost player, a reaction, hot headed player, always not far from a referee's punishment, who played for Manure.
Joe Shaw did at least get called up as reserve for a cap, and touring parties for none representative games, maybe Steve did also, I'm afraid I have no knowledge of that.
What ever, its all subjective, could be Joe Mercer could eclipse them all.
