Maybe the T207's inclusions and exclusions were based solely on economics. Perhaps it was a lot easier to sign up Lowdermilk and Lewis for a pittance than Cobb and Lajoie for big money.
I also think the set was put together in a haphazard fashion and the final series was to include some of the stars but who knows? Perhaps if the total set had come to fruition, we'd be showing PSA 5 Jacksons with a Cycle back or VGEX Lajoies with an Anonymous back and a G/VG Alexander with a Broadleaf back. The mysteries of this set run deep.
