Marcus Smart doesn't just disrupt opponents' offensive sets - he irritates the hell out of his teammates, particularly one that needed a bit of prodding. Gordon Hayward needed to become a little more aggressive on the court, so Marcus decided to get Gordon on track during practice.
In a recent practice, Gordon temporarily took over the James Harden role, and Smart, as always, played himself. Most of us remember Marcus prodding Harden into two quick offensive fouls. Well, this time Smart prodded Hayward into becoming more aggressive (per MassLive's Tom Westerholm):
The Celtics were embroiled in one of their toughest practices of the season, and they were poking and prodding at Hayward -- "fouling him and s---" as Marcus Morris put it.
