i think he will be fairly solid, but there is no way i would be starting him over ahman green in a flex. if your worried about PPR, ahman had 4 receptions last week, which i think will be consistent this season. ahmans yardage numbers will be consistently better while welker will be hit and miss IMO. anyone outside of moss seems risky in that offense due to bradys history of spreading the ball out. moss scares me too, but i like him a ton more than i do welker.
