The Baltimore Ravens are an alleged playoff contender with red flags surfacing in their passing attack.
Most worrisome, however, is first-round speedster Breshad Perriman, who has missed 14 straight practices with a strained tendon in his knee.
"I hate that he's missing it, hate that he's not out here," coach John Harbaugh conceded over the weekend. "I have a knot in the pit of my stomach in some ways about it. In other ways, I know it's all out of our control, and I'll put it in God's hands and let him take care of it. To me, that's the best strategy, right there."
Flacco needs Perriman to emerge as a dangerous playmaker capable of stretching the field vertically and horizontally.
If Perriman can't overtake special-teamer Kamar Aiken for the No. 2 job early in the season, opposing defenses will stack the box, daring Flacco to beat them over the top.
Here's what else we learned on Monday:
- On the same day that rookie tailback David Johnson (hamstring) returned to a limited practice, the Cardinalssigned ex-Titans backfield starChris Johnson to a one-year contract. Johnson will have three weeks to prove to coach Bruce Arians that he's a better second-fiddle to Andre Ellington than the team's third-round pick.
- In offensive line news, the Seahawks are shifting right tackle Justin Britt inside to guard after the 2014 second-rounder was clown-suited by Von Miller in the preseason opener. Garry Gilliam and Alvin Bailey will swing outside to vie for the right tackle job, leaving Russell Wilson's pass protection in peril -- once again.
- Redskins quarterbacks were in the news Monday, as Robert Griffin III's harmless self-motivation was taken out of context. Although RGIII understandably believes he can still become one of the game's best quarterbacks, ex-coach Mike Shanahan's comments in support of backup Kirk Cousinsraise an important question: which one gives the Redskins a better chance to win in 2015?
