A more recent example for why they are jumping the gun with Kershaw: my guy, Tim Lincecum. 2 Cy Youngs, dominate performances. No one is talking about him for the HOF at this point.
They're still praising his performance in Dazed and Confused though.
In that he went from zero mentions to Benner's one mention. (Bit of a self-fulfilling prophecy there, Benner.)
