Griffiths great strength was that he gave 100%. As others have said as a winger he needs pace, a good cross and natural ability, all of these he was lacking in. When compared side by side with Beeson there is no contest Bees has the greater ability and pace it is just if the new managers can get the best out of him, something Tommy Taylor couldn't do.
The hard work that Griffiths puts in undoubtedly make him an asset and a more reliable player but I personally think Bees has the greater potential if it can be realised.
