The most troubling position on the Dolphins' defense—and perhaps the entire team—is the outside linebacker spot.
Although Joey Porter's departure is addition by subtraction due to his rapidly declining, one-dimensional productivity and his cancerous presence, the losses of Porter and veteran Jason Taylor leave the Dolphins with little experience at outside linebacker.
Odds are rookie second-round pick Koa Misi will get every chance to start on the strong side, so we'll see right away if he can improve on his somewhat limited college productivity.
On the other side, versatile veteran backup Charlie Anderson will get his first real shot at starting in the NFL.
Although he doesn't have much overall productivity as an NFL linebacker, Anderson has had his moments, such as his six-tackle, two-sack, two-forced-fumble performance against the Buccaneers last season.
Providing Anderson the most competition will be second-year player Cameron Wake.
Although he played mostly defensive end when the Dolphins went to four-man fronts, Wake is a pure pass-rushing outside linebacker in the team's base 3-4 scheme.
Coming off an astounding 39 sacks in two seasons in the CFL, Wake showcased his pass-rushing ability as an NFL rookie in 2009 with 6.5 sacks in limited playing time.
If Wake can prove himself at least adequate against the run and in coverage, there is absolutely no way he will be relegated to a reserve role again in 2010.
Of course, those are big ifs.
