I think your analogy is incorrect. SCOTUS is the major leagues, not the hall. To be inducted, one must have retired from playing.
The little leagues would be outside the legal profession entirely. The civilian and government lawyer roles would be A or AA minor league. Circuit courts are the AAA farm club.
If an A farm team player has the capability of playing at the major leagues, and catches the eye of the scouts, then why can't they play in the majors? Just because they didn't work their way up through the system doesn't mean they don't have the ability to play at the top level.
I realize the 'flaw' of my analogy with the majors vs. the HOF. It was intentional. The SCOTUS is many times more prestigious than the MLB HoF.
Yeah, there are examples of those who went right to the majors like Dave Winfield. In this case there are 9 possible positions on the Supreme Court... just 9! Not even close to the best qualified person was selected. NOT EVEN CLOSE! President Bush wimped out on this selection.
I hope it works out. Counting on the 'benefit of the doubt' I habe no choice but to give President Bush.
