BEREA The Browns' offense is up and running, but the running game still needs work.
Jerome Harrison might be the extra hammer needed to finish the job.
Coming off the bye week, the Browns are averaging 115.2 rushing yards per game.
That's a beefy bump up from last year's pitiful 83.4, but it's acres behind AFC leader Pittsburgh's 159.0.
In the five games other than against Cincinnati's sieve of a defense, when Jamal Lewis ran for 216 yards and the team for 226, the Browns are rushing for a modest 93.0 yards a game.
A few factors could help catch the running game up to speed with a sharp passing game:
• Lewis' return from a foot injury that has cost him almost two full games. Head Coach Romeo Crennel seems optimistic Lewis can play Sunday at St. Louis.
• Continued maturation of the offensive line.
• Harrison pushing Jason Wright for playing time behind Lewis.
In his first action of 2006 after losing the No. 2 running back job to Wright, Harrison cut through the Dolphins for 57 yards on eight carries. He also had a 15-yard catch-and-run. He set the tone for a game-clinching, 67-yard touchdown drive with runs of 5, 13 and 9 yards.
Crennel doesn't rule out an expanded role for Harrison.
"If we feel like he gives us the best chance, then he'll get spotted in,'' the coach said Monday.
Wright exudes exemplary effort and attitude. He knows the offense inside out. He is a willing and effective blocker.
Harrison is quicker and more elusive, scooting through openings and making tacklers miss. At 5-foot-9 (if you believe the printed roster), he is the shortest Browns player. He has been run over while trying to block.
"It's not just blocking, it's everything," Crennel said. "That guy, that position, has to be able to run the ball inside, outside, catch the ball out of the backfield and pick up pass protection."
How much is Harrison hurt by his height?
"You'll see short guys get it done," Crennel said, noting 5-foot-11 Denver defensive end Elvis Dumervil helped wreck the Steelers on Sunday.
So, how much will Harrison play coming out of the bye?
"That depends on the game plan," Crennel said.
The Rams can be had by a good running team. They are allowing almost 130 rushing yards a game.
BLOCK PARTY
Crennel said Kevin Shaffer and Ryan Tucker will continue to share time at right tackle.
Platooning on the offensive line is almost as rare as rotating quarterbacks, but Crennel is hesitant to sit either of the veteran starters. Certainly, Tucker isn't going away after blocking on 66- and 67-yard scoring series against Miami in his second game back from a four-game suspension.
Crennel says rookie left tackle Joe Thomas is doing a "good job" at left tackle. As a No. 3 overall pick, he isn't going anywhere, either.
EMPTY WITHOUT 'O'
One reason St. Louis' season is buried in Mississippi River mud is losing left tackle Orlando Pace to a season-ending injury.
A former No. 1 overall pick out of Ohio State, Pace was a fixture on the Rams teams that reached Super Bowls in the 1999 and 2001 seasons.
Crennel had to scheme against Pace when he ran New England's defense in the latter Super Bowl.
"Pace was pretty good," Crennel said. "Some positions, like left tackle, cover corner, quarterback ... you need good skill at those positions if you're gonna have a chance to be successful."
Third-year pro Alex Barron has replaced Pace at left tackle. He was a No. 19 overall draft pick who is reminding scouts why it takes a higher pick than that to get a Pace.
