Rudy is not ideal as a starter that is true. But playing in an iso-offense with DeRozan and Aldridge usually results in one of those 3 having the mismatch. They were very efficient doing that last year, whoever had the mismatch got the ball in the post. Playing with Poeltl unleashes Lyles 3-point shooting cause Poeltl plays closer to the rim and Lyles can get open easier cause the bench plays more of a motion offense. Also him and Poeltl are both good offensive rebounders and the bench got more 3-point shooting than the starters. Lyles as a starter is literally the worst starting PF in the NBA.
As I said starting Gay ain't ideal, but I prefer that. What's concerning to me is that his 3-point shooting has fallen off a cliff recently
