Based purely on performance (not character clause), who is the worst player that YOU think should be in the Hall of Fame?

We talk plenty about the worst players who *are* in the hall, but who's the worst player who should be enshrined (whether they currently are or not)?

And on the flip side, who's the best player you think doesn't make the cut? Everybody has to have a line somewhere.

For this question I'm not super interested in pioneers or managers, nor character clause guys.
