Hypothetically, Draymond is exactly the caliber of player that could make this team into a title contender. Former DPOY, consistent 1st Team Defense, strength, defensive versatility, excellent passer, high motor, and, at times, respectable 3PT shooting. There's a reason that he's one of the best small ball 5's of this era, but after this past season, chemistry is major concern for anyone following this team. Draymond's strong and fiery personality has been great for GS because of the personalities (meaning that they're able to overcome or ignore his tantrums) and Kerr and Curry's leadership. I wouldn't want him on one of the youngest team's in the league, potentially causing a rift in the locker room.
I have and will continue to say that if the Celtics are going to pivot from Hayward, they have to take a good look at Aaron Gordon (Orlando would have to include another player/asset). Kevin O'Connor included him in a recent piece. He's been miscast as a 3 in Orlando when he has the potential to be what Draymond is, an above average 4 that can play small ball 5 and unlock a death lineup. He also fits the team's timeline.
I think that unless Hayward wants to leave, the team should stand pat. This team will go as Tatum and Brown go and not a moment too soon. Hayward for X scenarios are interesting, but unless the X is a real game changer that can play the 4 or 5, it's a waste of time.
