If given a choice at center between either 6’3” Gaffney or 6’9” Sanogo, we’d all choose Sanogo. He’s 6” taller, at the position where height matters most of all.
That said, I’d put a 7’3” (skilled) Clingan at center every day of the week. He’s 6 inches taller than Sanogo. 6 inches taller. Think about how large that is. Sanogo dwarfs Gaffney. Clingan dwarfs Sanogo.
Is Sanogo a legit center, size wise, in college? Absolutely. But Clingan has that once in a generation size. And he’s skilled.
If he comes here, he starts at some point his freshman year. Sanogo plays 4/5.
