This little bonus set was included only in the factory sets, so a few people may never have seen them.
4/7 are in the HOF, and Larkin and Griffey Jr will almost certainly make it, so that leaves only Will Clark.
Will dropped off the ballot after his first season when he only received 4.4% of the vote. Despite a great career, he probably won't get a lot of love from the veteran's committee either. He retired when he was 36 and still very productive. Had he stuck around for 3-4 more productive seasons, he may well have found a home in the hall.
