Perimeter defense has been an issue all season for the Philadelphia 76ers. It’s what happens when the team is only stocked with three true plus defenders: Joel Embiid, Ben Simmons and Jimmy Butler, one of whom is largely confined to the paint. In Friday’s 113-102 loss to the Indiana Pacers, though, it felt like every single rotation wing or guard beyond Simmons — JJ Redick, T.J. McConnell, Furkan Korkmaz and Landry Shamet — struggled mightily. Heck, even Shake Milton had a couple breakdowns in his three minutes of action.
