I dont know about that, maybe, but dont get me wrong I think Hayward is a better overall than DeRozan. But DeRozan is a good pure scorer. He can get you buckets almost any time. Hayward stepped up in the playoffs big time. But they are close to, or in the same tier of player and having another player of that caliber would help us a lot, especially in the playoffs.
FYI Haywards usage % was 27.6 to DeRozans 34.3. In the playoffs this year Hayward went up to 28.5% and DeRozan came down to 29.6. That is not that big of a gap. Per 100 possessions DeRozan averaged 39.1 points per game to Haywards 33.4. Hayward did out perform DeRozan in the playoffs this year.
Hill, DeRozan, Hayard and Gobert is a solid 4 players in the playoffs if healthy. I think that pushes GS and is the second best team in the West next year and if the landscape is the same the 2nd best team in the NBA.
