There's nothing wrong with making a "Mussina > Blyleven" case, but this definitely isn't the way to do it.
Are you referring to my post as a case for or against the Mussina/Blyleven argument?.
Because my post was meant to show that the two are not that similar and so Blyleven not being in the HoF should have no effect on whether or not Mussina gets in.
