Fantasy Upside
He's the greatest quarterback of all time and has not shown any signs of slowing down. He's been a top-three quarterback in points per game for three consecutive seasons. Brady is as safe as they come as a top-five quarterback.
Fantasy Downside
The downside with Brady, as with any elite fantasy quarterback, is his value relative to cost. Brady's ADP means you'll likely have to spend a pick on him in the first five rounds, often earlier in casual leagues. In redraft leagues, he also showed some inconsistencies from his expected elite self last season, with nine fantasy weeks of less than 18 fantasy points.
2018 Bottom Line
Brady should be a lock to again finish as a top-five fantasy quarterback. The only question you must ask yourself is if you are okay with being thinner at RB and/or WR if you use the early pick required to take Brady.
