Hi John.
OK - like at least many hundreds of people at the time - the guy kind of resembles Chief Meyers. So what? He is not in a Giant's uniform, he is not with easily recognizable team-mates. He is just a guy in an old photo in a suit that resembles Meyers. That alone means that it is very highly unlikley that it is Meyers.
As to analysis - the ear mis-match is striking - we know for sure it is not Meyers. (also the nose is way different). It's also not McLean - Leon go get your money back.
