Here are some of the most important usage statistics through Week 2:

• Christian McCaffrey again played 100% of snaps. In Week 1 he was a stud and in Week 2 he was a dud, but his snap count stayed at the max. His success will likely depend on game script and on Cam Newton’s effectiveness.
  
  
• Five backs other than McCaffrey played over 70% of snaps: Leonard Fournette, Saquon Barkley, Ezekiel Elliott, Austin Ekeler, and Dalvin Cook. More often than not, a high snap count will lead to more opportunity and better stats. In Fournette’s case, I would advise patience as he is the only one of the group underperforming.

• Alvin Kamara played 65% of snaps while Todd Gurley played 64%. It was expected that the Rams would scale back Gurley’s snaps, but it was a bit of a surprise to see Kamara’s percentage decrease by 11 percent, particularly in a game where the Saints trailed throughout.

• Peyton Barber jumped from 36% of snaps in Week 1 to 65% of snaps in Week 2. It is impossible to tell if that trend will continue or if head coach Bruce Arians will continue to tweak his backfield week to week.

• Carlos Hyde played on 61% of the Texans snaps, and garnered 20 carries to Duke Johnson’s 6. Hyde is the lead back in Houston.

• Aaron Jones’ snap percentage remained steady at 59%. He just did a lot more with them in Week 2 (23-116-1; 4-34-0). This was the second straight week he faced a stout defense, indicating big things are coming for him this season.

• Chris Carson fell from 77% of snaps to 54%, as Rashaad Penny had a nice day (10-62-1). Penny had 11 touches to Carson’s 18. What looked like a dominant hold on the rushing work for Carson now looks much more like a timeshare.

• Derrick Henry and Dion Lewis each got 50% of the snaps. Now might be an excellent time to sell Derrick Henry.

• Notable running backs who played under 50% of snaps: Sony Michel (49%), Phillip Lindsay (48%), Josh Jacobs (46%), David Montgomery (44%), Miles Sanders (43%), Tarik Cohen (38%), Devin Singletary (33%). All are risky given this low snap count, although be aware it could be related to game flow or matchup.

• Tarik Cohen went from 70% snap count in Week 1 (mostly playing as a slot receiver) to 38% snap count in Week 2. Not a good sign for consistent fantasy production.

• Robert Woods had an off game (2-33; 1-9) but played on 99% of snaps.

• With injuries to Alshon Jeffery and DeSean Jackson; Nelson Agholor, JJ Arcega-Whiteside, and Mack Hollins moved into every-down roles (all over 85% of snaps).

• Demarcus Robinson played on 91% of snaps for the Chiefs. He is worth a start for as long as Tyreek Hill remains out of the lineup.

• Stefon Diggs went from 60% to 89% of snaps in Week 2. He only had one reception but had seven targets, so better days are ahead.

• Marquez Valdes-Scantling had a rough day as well, but played in 88% of snaps (Allison played only 46% of snaps).

• The wide receiver snaps for Jacksonville were again dominated by D.J. Chark (82%), Chris Conley (85%), and Dede Westbook (87%).

• Deon Cain jumped from 17% of snaps to 46%. However, he wasn’t targeted. Chester Rogers (40%) got 4 targets. For Cain to be relevant, he needs to jump into the 60-70% range.

• Hunter Renfrow jumped from 28% to 75% of snaps and led the team in targets with 8. He is worth a speculative add if you have a deep bench.

• Antonio Brown played in only 33% of snaps, yet had 8 targets, by far the most on the team. His usage was limited because he is still learning the offense and the game was a blowout.

• Miami’s Preston Williams jumped to 68% of the snaps. If the offense improves at all, he could become relevant quickly.

• Marquise Brown played in 65% of snaps, up from only 18% in Week 1. He received 13 targets! The coaches are apparently comfortable with his health, and he looks to be locked in as a starter in this exciting Ravens offense.

• Anthony Miller jumped to 52% of snaps, which is likely the reason Cohen’s snap count fell. Miller only got 1 target, however.

• Dante Pettis jumped from 3% to 49% of snaps. However, he did not have a target. It is difficult to tell if there is an issue between Pettis and Shanahan or Pettis and Garoppolo. For him to have any fantasy value at all, the issue(s) must get fixed.

• Cole Beasley fell from 70% to 49% of snaps. It is likely because the Bills took a lead on the Giants and shifted to a ball-control offense.

• Snap percentage for the 49ers receivers: Goodwin 51%, Pettis 49%, James 46%, Samuel 40%, Bourne 32%. Until they figure out how they want to play offense, avoid them all.

• A.J. Brown did not receive a significant increase in his snap count (45%), even after an excellent Week 1

• Donte Moncrief fell from 90% of snaps to 32%, as I would have expected. He is playing poorly.

• KeeSean Johnson of the Cardinals fell from 76% of snaps to 32%. He can be dropped, as Michael Crabtree is stealing his opportunities.

• Darren Waller played 95% of snaps (100% last week). He is a top-10 tight end.

• O.J. Howard had zero stats on 92% of snaps. He appears to be in Bruce Arians’ dog house who stated this week: Howard can play "a heck of a lot better than he's playing."

• Virgil Green played on 88% of snaps after Hunter Henry’s injury but only had two targets.

• T.J. Hockenson played on a higher percentage of snaps in Week 2, but obviously struggled to get free. The defense likely schemed to take him away.

• Gerald Everett played on 71% of snaps, up from 39% in Week 1. If that continues, his production will increase.

• George Kittle’s snap count fell from 91% to 67%. What is Kyle Shanahan doing?

• Matt LaCosse played in 58% of the Patriots snaps, catching 2 passes. He may be worth a speculative add for those hurting at tight end.

• Unbelievably, Mark Andrews played only 53% of the snaps while playing 42% in Week 1. He is the top-scoring tight end in the league. Imagine if he was playing 90% of snaps.
