Once Hayward returns, it will round out the Celtic's starting 5 on both ends of the court, and will make them THAT much stronger then they are right now.
With Rozier and Morris already providing some two-way production off the bench, and Smart and Baynes carrying that second unit defensively, I feel like this Celtics squad is one consistent bench scorer away from being just as dominant offensively as they are defensively, come next season.
add one consistent double-figure scoring to this second unit (Rozier, Smart, XXXX, Morris, Baynes) to compliment that starting five (Kyrie, Brown, Hayward, Tatum, Horford) and I genuinely believe that this team could beat the Warriors in a 7 game series.
