Raptors looking for more offense in pivotal Game 4

Their season isn't over if they lose Game 4 of their Eastern Conference semifinals series with the Philadelphia 76ers on Sunday (3:30 p.m. ET, ABC), but this is as pivotal as a Game 4 can get. A win draws the Raptors even at 2-2, with two of the last three games in Toronto. A loss puts them in a 3-1 hole that few teams have climbed out of.
