I don't like Embiid winning with only playing a third of the season. I know it's a different sport, but if Gary Sanchez couldn't win while putting up better numbers than Babe Ruth for a third of last MLB season, Embiid shouldn't win while putting up an all-star caliber, but not historic performance for a similar amount of time in the NBA.
With regard to Saric, he has significant previous professional experience and is playing on a lousy team where he gets significant minutes. If team contribution matters, Brown should win hands down, as he was able to fill a starting slot on a top 5 team, and actually improved his game while doing it. Even if Saric averaged 25ppg, his team would still stink, and he'd be home watching the playoffs.
