Sanderson is on the far left. I haven't heard why these players were picked or if there are others from the past that will get a ring.
Sanderson came to the Cubs before the 1984 season in a three-way deal with the Cubs, Expos, and Padres. It was a homecoming for Sanderson, as he grew up in suburban Northbook. He spent six seasons with the Cubs and was an even 42-42.
I've got 38 cards of Sanderson. Since he was never a top star, he wasn't included in much above the base sets.
