+ There’s no player that excites me more than C.J. Spiller heading into the 2013 season. He’s going to be the focal point of Doug Marrone and Nathaniel Hackett’s up-tempo, run-heavy offense in Buffalo. He flashed his speed and strength against Minnesota on Saturday, knifing through the defense while displaying quick feet. It’s just too bad that he’ll face 8-man fronts all season.

+ Speaking of the Bills, their pass rush looked good against the Vikings. There were times when Jerry Hughes ran himself out of plays but he has great acceleration off the snap. He, Manny Lawson and Marcell Dareus stood out, but the entire starting front seven for Buffalo had a solid night.

+ The transition from Rob Chudzinski to Mike Shula in Carolina hasn’t been seamless for Cam Newton. On Thursday night in Philadelphia, Newton struggled with errant passes, throwing receivers open and hitting targets in stride. Most of his completions came with receivers coming back to the ball, which is fine if a quarterback is accurate. But Newton completed 57.7% of his passes a year ago and thus far in preseason he’s 11-for-23 (47%). Shula figured to rely heavily on DeAngelo Williams and the running game, and it’s unlikely that that plan has changed.

+ Nick Foles was 6-for-8 for 53 yards and a rushing touchdown on Thursday night against Carolina, but Michael Vick was clearly the more efficient quarterback. He was poised and confident in the pocket, displayed good mobility while extending plays with his feet, and got the ball out of his hand quickly (a requisite in Chip Kelly’s offense). While Kelly has avoided naming a starter for Week 1, it’s safe to assume Vick is the current frontrunner…

+ …Now, whether or not Kelly can keep Vick healthy is a different subject altogether. Kelly’s offense will be predicated on short-to-intermediate passing out of multiple personnel groupings and formations. The read option also appears to be a key feature, which suits Vick’s skill set but also puts him at risk for injury. Even if Foles doesn’t win the starting job out of camp, history tells us that Vick’s backup needs to be ready at a moment’s notice. It’s only a matter of time before the veteran suffers some sort of aliment.

+ We’ll see what happens when opponents start game planning to beat them on Sundays but thus far the Browns have been intriguing. Brandon Weeden looks comfortable and confident running Norv Turner’s offense and a star is rising in tight end Jordan Cameron, who made an incredible catch for a touchdown versus the Lions on Thursday night (one of his two scoring receptions in the game). Save for guard John Greco (who was manhandled by Nick Fairley on consecutive plays in the first half), the offensive line has also performed well and the defense might turn out to be the most underrated unit in the NFL by seasons end. Usually it takes about 10 games before Ray Horton’s system takes hold but his players in Cleveland have taken to it like a fish to water.

+ Dirk Koetter finally has his power running game to complement his vertical passing attack in Atlanta. The Falcons ran Steven Jackson out of the “11” and “12” personnel groupings on Thursday night in Baltimore, trying to match hat-for-hat and allowing him to do what he does best: Run downhill. Thanks to Matt Ryan and his assortment of weapons in the passing game, that offense was already difficult to stop. If they can build a lead and then run clock in the second half of games, they’ll avoid having what happened in the NFC title game when they allowed the 49ers to erase a 17-point deficit.

+ It’s becoming evident that the Ravens will be held back by their lack of weapons in the passing game. Torrey Smith took a simple slant for a touchdown against the Falcons on Thursday but William Moore also took a horrible angle on the play and turned a 7-yard gain into a 77-yard score. Without Dennis Pitta and Anquan Boldin drawing attention in the short-to-intermediate game, opponents will likely bracket Smith in coverage and force somebody else to beat them. Visanthe Shiancoe won’t be that somebody else.

+ The run-blocking units for San Diego and Chicago had good nights on Thursday. Matt Forte finished with a 9.2 average and Ryan Mathews rushed for 5.0 yards per clip, as both running backs flashed burst and acceleration through open lanes. Rookie Kyle Long stood out for Chicago, as he consistently was stout at the point of attack and finished blocks in the running game. Sadly though, Philip Rivers was often on his back and Jay Cutler had pass rushers around his feet throughout the first quarter. Pass protection will be a major question mark for both teams all season.

+ Alex Smith completed 7-of-8 passes last week against a Saints team that played a soft zone, but he struggled against a more aggressive 49er defense on Saturday. He’ll be able to dink and dunk past lesser opponents but what happens when the Chiefs are trailing and he has to beat opponents vertically in the fourth quarter? There’s no question he’s an upgrade over Matt Cassel and Kansas City is going to win a few contests on Andy Reid’s game-planning alone. But Smith remains limited as a passer and thus, it’s hard envisioning the Chiefs beating teams like Denver or New England if they’re able to make it to the postseason.
