Williams has shown toughness and some ability to create leverage and shed blocks, but Riddick isn't sold on him.

"I wasn't that high on him coming out of college and haven't seen anything to change my opinion," Riddick said. "He's an early-down run plugger who can be caught with his head down and snatched and thrown to the ground. I don't see any huge upside, but maybe he'll prove me wrong."

While the Ravens' top three draft picks have defined roles, fourth-round fullback Kyle Juszczyk and linebacker John Simon have been limited to special teams, with fifth-round offensive tackle Rick Wagner playing occasionally on offense in extra-lineman packages. He's the top backup at left tackle and right tackle.

Marlon Brown overcame the odds to make the final roster after tearing his anterior cruciate ligament last November while playing for Georgia.

At 6-5, 205 pounds, Brown is a large downfield target. That has enabled him to be competitive right away.

"He looks just like he did in college — lots of inside-outside versatility, good hands, tough and deceptive speed after the catch," Riddick said. "He can eat up ground with long strides. I think he should win more contested jump balls and isn't going to separate much downfield, but they've gotten everything you could want out of him as an undrafted guy."

Brown has 26 receptions for 297 yards and is averaging 11.4 yards per catch. His longest was a 59-yarder against Green Bay, a play on which he displayed an ability to accelerate after catching the ball on a short route. Brown caught a career-high two touchdown passes and added a two-point conversion Sunday, contributing 14 points in the Ravens' loss to the Cleveland Browns.

"It's like a dream come true for my rookie season," Brown said. "I can definitely get better and become a more fine-tuned receiver and understand coverages better. I'm pleased right now, but I can definitely get way better."
