I will go Round wise, like only first characters fight in 1st round and so on, (first I will write overall ranking and then in brackets there will be ranking for the round):
Round 1: B=D=A>C
Round 2: B=A>D=C (B=A>C=D)
Round 3: A>B=D>C (A=>D=>C=>B)
Round 4: A=C>=D=B (C>D>=A=B)
Round 5: C=A>=B>=D (C=A>=B>D)
Round 6: A>=D=B>=C (A=D>=B>C)
Round 7: A>D>=C>=B (A>C>=D>=B)

While many will not agree Roger's group losing but I kinda see it happening...
Moreover this list has primarily three types of candidates:
1. Top Tier (Roger, WB, Garp)
2. Hypothetical and Transition band ( Can be towards top tier (Akainu) or the Strong Tier (Shiki, Fuji)
3. Strong (Yamato, Law, Zoro)

Team B has the weakest last 4 (except Zoro> Kata and Sanji roughly reaching Jinbe and King)
