The two categories for the Perfect Celtic thus far have been best passer and top shooter/scorer. Larry Bird took both of those. Now we are on to the best perimeter defender - and there are a lot of choices.
We can go all the way back to K. C. Jones. In the same era, Larry Siegfried, can't be forgotten. Johnny Most's "Ziggy's in his shirt" was often heard between Johnny's puffing on a cigarette. Sam Jones brought up Larry's name to me out of the blue as a tough defender.
