Alex Smith had his second-best fantasy game of the year in Week 15, throwing for 297 yards and 2 touchdowns, good for 21.6 fantasy points.
Smith has apparently rediscovered his fantasy floor, averaging 17.1 fantasy points per contest in his last four games while averaging 244.3 yards and 1.8 touchdowns.
Facing Pittsburgh next week, Smith will likely be forced to throw because of the rate at which the Steelers are putting points on the board. Since a Week 12 bye, Pittsburgh has given up 298.0 yards and 3.0 touchdowns per game in three contests, good for 25.6 fantasy points to opposing quarterbacks.
Smith hasn't touched 23 fantasy points all year, but it's tough to see any way that he fails to produce some solid points in this matchup.
