Jason Parker wasn't even as good as Marquis Estill.
So no. Just no. Parker has been mythologized far beyond his actual ability. Sad that he blew out his knee, and sad that he couldn't stay out of trouble, but he was never going to be that great of a player. He was a thickly built undersized center with 0 shooting ability. Good for some ferocious dunks, a nice rebounder, but not much else.
Cal actually had a very similar player at Memphis with Joey Dorsey (though I think Dorsey was a lot quicker and a much better all-around athlete). Dorsey actually did get a cup of coffee in the NBA, but he was not a high draft pick.
