I want him in the forwards because he has no business being on the wing.
While Manu may have some flaws he still has good top end speed and always had surprising acceleration (when not required to turn). He could finish with the best of them. Hands and defense (mainly positioning) were the two things that let him down. Despite that he's often been referred to as one of, if not the best winger in the comp at various times.
Maumalo has all of Manu's weaknesses without the positives in regards to wing play. He's got size, that's about it. Doesn't have the speed or acceleration and can't finish. Has no business being on the wing and trying to manufacture him to play there is simply ruining any chances he has of having a successful career.
Would loved to be proven wrong on this, but I don't see it happening sadly.
