A great coach can raise the floor of a mediocre team in the NBA. We've seen it time and again — upstart teams often find their spark through the tutelage of a great coach. Maybe said coach is an elite play designer, maybe their rotations are flawless, maybe they connect with the players and bring the best out of their roster.
Whatever the case, it's not uncommon for a team to find success thanks to coaching... until it's time to compete with the best in the league deep in the playoffs. That's usually when a lack of roster talent catches up to a team, and that's the situation JJ Redick might be facing in year two.
