Gabriel, Slater, Tarver and Young don't seem to have much character, though Young is out now so I guess he's not much of a problem.
Gabriel is an awful talker, but I think they've done well with him, that psycho stare before the
450 Splash is awesome!
Heath Slater has only just shown personality this past week when
Cena made fun of him then he had that spot with
Edge. On the show he was the
One Man Rock Band and as a babyface I always saw him as a
Bill & Ted like character.
Tarver was bland on the show too.
Young was billed as a party guy who the
SES kept trying to convert.
I haven't seen any of this season's rookies except when they've appeared on Raw or SD so I can't really guess how well they'd fit in with Nexus.
Out of the current crop,
Harris could replace
Sheffield,
Riley and
McGillicuty could fit in, but should only get a spot if its high profile, they are too good to be lackeys.
And dude you should watch the show, its quality!
