Well, we have to replace Hamonic, Holden and Zaitsev next year. We have Zub, Chabot, Sanderson and presumably Brannstrom lacking up the left side and top RHD. So there top 7 spots to fill.
JBD should take one spot. Another spot is for a 7th Dman, so we still need to figure out a top 6 d spot.
If You don't think Fabbro is good enough top play in the top 4, or you think JBD is and would rather use another ELC or bargain deal for the third pair, that's fine. But JBD can only fill one spot, we need more than just him.
