He is wrong.
Mussina will be carried over to next year. He has already hit the minimum mark required for 5%. If the same number of voters vote this year as they did last year, he needs 28 votes to be carried over. He currently has 42 public votes. I doubt voters have increased from 568 to 841.
It also means Trammel, Martinez, and Smith will be carried over.
Guys like Kent, McGriff, Walker, McGwire, Sosa, Raffy, and Mattingly have slight to significant concerns hitting that 5% mark.
