Late in the game, that is a possession where I would like to see Sully step inside and take that 18 footer. A shot where he could probably hit 40-42% of the time versus 30% of the time from the three point spot.
The eFG% doesn't mean as much in that situation. Play those percentages earlier in the game. But late in the game, take the shot you make more regularly. Take the easier shot. Just needed a basket.
In that situation = FG% over eFG%
