The first week of the NFL preseason is in the books -- and while most key players didn't play much, there was enough action from a few players looking to make an impact around the league. A strong camp combined with a good performance in the first game has a few players on the upswing. It's not all positive, however, with others seeing their stock drop.
Here'e a look at who's rising and who's falling one week in.
After an impressive start to training camp, Mathieu's impact in his preseason debut was obvious. The Cardinals used Mathieu in a few roles and he went on to tally a sack, two tackles and a 24-yard punt return. Arizona head coach Bruce Arians said Mathieu was all over the field and plays big enough to play safety full-time.
His preseason performance came just a few days after a scout called the rookie safety Arizona's best "pound-for-pound" player. The third-round pick appears to be past any issues he had at LSU and on his way to earning a starting job as a rookie.
DeSean Jackson is coming off a down season, but is reportedly "rejuvenated" under new head coach Chip Kelly. With Jeremy Maclin out for the season, Jackson is Philadelphia's main receiving threat. He's responded with strong practices throughout training camp.
Those performances carried over to the field where Jackson burned Aqib Talib for a 47-yard touchdown on his only target of the game. Jackson could be close to rejoining the discussion as the most dangerous deep threat in the NFL if he keeps up his season-opening performance.
There isn't much question Bradshaw can produce when healthy. The question is, is he healthy? Bradshaw has been limited by foot injuries in recent seasons and those carried over to the start of training camp with the Colts.
He's progressed to the point where he's able to return to practice and he was activated from the physically unable to perform list on Monday. The foot injury could still be an issue heading into the season, but for now he continues to make steady progress in his return.
After not catching a pass all of last season -- despite being healthy and a first-round pick -- Jenkins enters his second season with an opportunity to play a bigger role. He's yet to to take advantage, however, playing behind a former undrafted free agent in the first week of the preseason.
Jenkins caught one pass for 11 yards in the game, but fumbled after hauling in the pass. Jim Harbaugh said Jenkins' performance "could have been better." San Francisco offensive coordinator Greg Roman said Jenkins is improving, but lacks consistency while Matt Maiocco of CSN Bay Area recently suggested Jenkins could be fighting for a roster spot.
Webb was never likely to be the future at quarterback in Minnesota, however, now he's on the fringe of making the roster. Webb moved to wide receiver this offseason and will have an uphill battle to make Minnesota's final 53-man roster.
Vikings head coach Lezlie Frazier said Webb will be evaluated as a wide receiver and his ability to play quarterback won't do much to help his chances to make the roster. Having played quarterback in college and during his NFL career, Webb has a lot of ground to make up on the other wide receivers battling for a roster spot. He caught two passes for 11 yards in the preseason opener.
When the Bears signed Jermon Bushrod, Webb lost his job as Chicago's starting left tackle. He was expected to transition to being a right-side starter, but is now fighting for that starting job as well. Following Chicago's preseason opener, rookie fifth-round pick Jordan Mills -- not Webb -- saw most of the action with the first team.
Preseason MVP contenders:
With 25 percent of the preseason in the books, who are the contenders for the coveted title of the NFL's Mr. August?
1. LeGarrette Blount, RB, Patriots -- The NFL's preseason rushing leader, Blount is the obvious pick for MVP after the display he put on against Philadlephia. His 51-yard touchdown run made observers around the league say Adrian who?
2. Tarvaris Jackson, QB, Seahawks -- It's hard to get much better than perfect and that's what Jackson was against San Diego, posting a perfect 158.3 passer rating. He threw for two touchdowns while completing 8-of-9 pass attempts. He's averaging 14.2 yards per attempt, which would obliterate Sid Luckman's NFL record of 10.9.
3. Jeff Tuel, QB, Bills -- Tuel currently leads the NFL is passer rating among players with at least 10 pass attempts. He completed 82.6 percent of his passes in the preseason opener and threw for two touchdowns. It's only a matter of time before there's a QB controversy between the undrafted Tuel and first-round pick EJ Manuel in Buffalo.
