Video: Week 5 Waiver Wire Has Upside
I would only consider Keon or Khalil Shakir if we get official word that DJ Moore is going to be missing a considerable amount of time. But even in that instance, I would say these are guys that aren't going to be league winners.

Desperation flex play if DJ Moore is sidelined

Keon Coleman is a deep-format by-week fill-in. He is only a viable desperation flex play if DJ Moore misses significant time; historical data shows he averaged 7.8 fantasy points per game (WR59) in games without Moore last season.
