I warned about overreactions to Week 1 in this space and in the paper column last Friday. Those that stuck with the likes of Kevin Ogletree, Mark Sanchez, Stephen Hill, Dexter McCluster and others got burned.
Here's what we need to know as the dust from Week 2 settles:
* Robert Griffin III is not one of the "fluky" Week 1 guys. Any quarterback that has elite running ability is going to sustain fantasy value. He's the real deal.
* Sam Bradford loves him some Danny Amendola. He could catch 90 balls this year, but don't expect touchdowns or big-time yardage.
* I'm not worried about Darren McFadden. It will come as he gets used to the new Greg Knapp scheme.
* I am worried about Chris Johnson. His offensive line is a disaster and he's lost all confidence in what holes to hit.
* It's hard to trust anyone in the Texans' passing game. They are just so dominant running the ball. Why pass?
* C.J. Spiller may be the most explosive running back in the NFL. He's going to be a top-5 option for at least the next month. He could even keep the starting job once Fred Jackson gets back.
* The Cowboys trailed for the entire game and Kevin Ogletree saw one target.
* Aaron Hernandez's injury is brutal. He's expected to miss as much as six weeks. It will give Wes Welker some more playing time, though.
* Certain guys you have to play even though you know they're hurting. Hakeem Nicks is one of those guys. Special, special talent.
* Ryan Mathews should be back for Week 3. This is your final warning: The guy is going to be a weekly RB1 with No. 1 overall upside.
* Dexter McCluster is just a slot receiver in a weak passing attack. The only appeal is that he's eligible at RB in some formats. That's useful if you get in a pinch.
