Fffft, you evos just make this up as you go along. First it's Indianapolis Man evolved from Baltimore Man, now it's the other way around. Can't you silly evos make up your mind.
Oh, and if your theories are true where are all the transitionals like half Indianapolis Man and half Baltimore Man?
I mean has anyone ever witnessed a Baltimore Man turn into an Indianapolis Man?
Or better yet, has a Baltimore Man ever given birth to an Indianapolis Man?
No? Well, I thought as much.
Take for example, the picture on the cover of this 1938 issue of Life Magazine. This specimen was briefly listed as an early Pittsburgh Man. However, famed trader of the day George Halas realized that the specimen in question would be a much better fit as Chicago Man, and acquired him in 1939. Note the primitive head covering, as compared to what we now call Pittsburgh Man.
As a former Baltimore Colt fan, let me just say ... don't get me started.
