The 4 and 5 both play under the basket. And Griner doesn't get blown by. That's what makes her so special. She's big but she's also mobile unlike Cain, Dydek, Feenstra, and Dehaan. And it's not like those forwards would have her out at half court sizing her up or even the 3-point line. Griner could definitely guard those fours with ease. Meanwhile with most of them 5-7 inches shorter than her, she can shoot her turnaround jumpers and out to the free throw line with ease.
And I never said Glory would be the ideal 3 on the offensive side. Once again, I was speculating about their defensive possibilities with the additions of Cambage and Griner. I am more aware than most people on this board that Glory doesn't have much of a perimeter game at this point in her career.
The league hasn't seen a player like Griner, ever. And we've barely have seen what Cambage can do. She may end up being one of if not the only post players who can compete with Griner. Why would you give her to another team?
In my opinion, it would be one hell of a twin towers experiment. Yes, EDD would probably fit into their traditional line up better, or trading Cambage and keeping Griner could give them some nice options, but good, even great wings and forwards are a lot more common than 6'8" post players...
