After a promising rookie season, Pierce turned in a disastrous 2013 campaign, hampered by shoulder, hamstring, toe and knee injuries behind a blocking scheme that failed to consistently open holes.
Now healthy, Pierce is optimistic about a bounce-back season in new coordinator Gary Kubiak's successful zone-blocking scheme.
"The running game is definitely a lot simpler than what we had the year before," Pierce said. "We actually did this in college. I definitely like the zone scheme. I'm used to it. I got a knack for this kind of offense."
