Embiid has lost 25lbs in order to stay healthier this season. Good news for 76ers fans. He was carrying too much weight.
On the opposite end of things, Orlando's Jonathon Isaac gained a huge amount of weight and now weighs 250lbs. Looks like he is trying to convert to being a big man rather than the combo forward he was at his lower weight (220lbs-230lbs).
They were playing him a fair bit at center towards the end of last season. I did not like him there. He doesn't understand the position. He still played like a forward instead of a big man (back line of defense, main rebounder, main roll threat). I like Isaac better as a 6th man where they can keep 2 of their 3 forwards (Isaac, Banchero, F Wagner) on the court at all times to keep the pressure up on their opposition.
