You’ve just been dealt a crushing fantasy football defeat. You know what that means: Time to panic! Except, no. Please don’t.

Week 1 is in officially in the books! Which means the fantasy talk around the water cooler is as predictable as death and taxes. Why did I play that guy? He’s so overrated! Who wants a trade? I gotta make a move!

Ladies and gentlemen, welcome to the “Knee-Jerk Reaction” week. Irrational conclusions based on one small subset of data. Just one snapshot out of 16 games.

Panic sets in for all fantasy owners during “Knee jerk Reaction week.” If a player performed well, he’s set for the season. If an early-round draft pick bombed out, trade talks are initiated immediately. It’s the nature of a fantasy football owner to overreact, and this leads to some great opportunities to buy low or sell high.

This week’s 50 Shades of Fantasy Football takes a look at those players who had a Week 1 performance that will not be indicative their season long production. Whether they’re the players that performed great in but are destined to regress backwards in upcoming weeks, or those disappointments who have every chance of erupting in Week 2 — and beyond. No matter last weekend’s results, we encourage you to stay the fantasy football course! Continue to believe in your team and keep a level head.

We’ll start with the Buy Low candidates, followed by the Sell High high guys.

Onward!
