OK, I will be the one...
I nominate Hal Chase.
He was eventually proven to be a crooked ballplayer; however, appears on five different T206 cards...including two of the six "Super Prints." The other four are Cobb, Evers, Chance, and Matty.
To me, that speaks to his popularity. And another Hal Chase card depicts him holding a trophy. Clearly, he was an early hobby darling.
The ATC had their finger on the pulse of Baseball and knew what they were doing, right?
So, in summary, he was a great ballplayer in 1909, even if he was a bit shady. My opinion is that he would have been voted in. After all, induction into the Hall is just as much a popularity contest as anything else.
Best regards,
Eric
