Of the remaining players, I would cast a vote for:
Ken Griffey Jr.
Trevor Hoffman (can't not vote for him, after making the case for Lee Smith and Billy Wagner)
No need to justify Bonds and Junior. As for Trammell,comparing him to other shorstops he should be in. He has a higher JAWS than some Jeter guy and essentially the same WAR as Barry Larkin. He was overshadowed by Ripken during his career so may not have gotten as much recognition as he deserved, even being robbed of a well earned 1987 MVP. Alas, by the time the voters recognized the extent of his full accomplishments the ballots were too crowded and there was no room for him.
