I think we're already taking a chance with AD and Lebron. Iggy can be a leader on the team and i'd put money on him to hit a shot when it matters.
Crunch-time lineup with LeBron running the plays:
Bradley vs. Lou Will
Green vs. Shamet
Iggy vs. Kawhi
LeBron vs. PG13
AD vs. Zubac
Interesting thought, eh? Lakers scoring in the frontcourt and Clippers scoring on the perimeter, both teams loaded with perimeter defenders but the Lakers better inside, Clippers threats a little better balanced but that AD vs. Zubac matchup looms large. But it only works if Iggy still has the athleticism to keep up as an elite defender. I remember when Bruce Bowen, Ron Artest, Shane Battier reached that age and the drop-off was enormous. If Iggy is only hitting 30% of his threes and can't keep up with Kawhi, then it's tough to say that he'd be a difference-maker.
