NFL Notes: 49ers, Cardinals, Dolphins, Giants, Rams, Seahawks, & Texans

49ers

• OT Jonathan Martin is struggling as a starter and probably needs to show more to secure a spot as a backup. (Bill Williamson)
• Defensive linemen Quinton Dial and Tank Carradine have both been stars in 49ers’ camp thus far. (Bill Williamson)

Cardinals

• Third-round pick WR John Brown has the No. 4 receiver job all but locked up. (Josh Weinfuss)
• Veteran Larry Foote has shown that he can still be a three-down linebacker. (Josh Weinfuss)
• K Jay Feely‘s time with the Cardinals could be coming to an end. (Josh Weinfuss)

Dolphins

• WR Mike Wallace mentioned that he will play in the Saturday’s second preseason game. (Adam Beasley)

Giants

• “At least one person in [the Giants] organization” had a first-round grade on RB Andre Williams and VP of player evaluation Marc Ross gave him as a “borderline second/third-round grade.” (Jordan Raanan)

Rams

• First-round pick DT Aaron Donald may not be a day-one starter, but he can expect to see plenty of playing time. (Nick Wagoner)
• Undrafted rookies TE Alex Bayer and DL Ethan Westbrooks are both in the mix to secure a roster spot. (Nick Wagoner)
• RB Benny Cunningham is someone to keep an eye on given that he is now “bigger, stronger and faster.” (Nick Wagoner)

Seahawks

• Second-round pick WR Paul Richardson has been the most impressive young playing in Seahawks camp. (Terry Blount)
• Undrafted rookie LB Brock Coyle has been the biggest surprise given that he’s very fundamentally sound for a rookie. (Terry Blount)

Texans

• QB Case Keenum took some reps with the first-team offense during Thursday’s practice. (Tania Ganguli)
