The Steelers are a contender year in and year out because they are a deep team. However, with a lot of young, talented players deep on the depth chart, it is time for the Steelers to free some room.
Mewelde Moore has served his purpose, but it is time to move on.
Even though he is only 28, Moore has shown the signs of aging. His yards per carry has dropped each year with the Steelers, from 4.2 in 2008, to 3.4 in 2009 and only 3.0 yards per carry last season.
His blocking has not been up to par either, and he is not enough of a third-down receiving threat to justify making the team. Pittsburgh has two young backs in Jonathan Dwyer and Baron Batch who can compete for this role, as well as Isaac Redman or even another free agent.
Trai Essex has been a backup starting 25 games at both tackle and guard over his six years with the team, and Jonathan Scott, in his first year with the team, started nine games at left tackle.
Pittsburgh should choose one of these veteran linemen and go with younger players with higher upsides who could fill a backup role.
The Steelers have plenty of choices with rookie Marcus Gilbert, Chris Scott and Ramon Foster. All three are potentially versatile enough to play guard and tackle.
Both Essex and Scott are 28, and while Essex would likely come at a lower cost, Scott is a better player.
Keyaron Fox had been the Steelers' special teams ace and a very valuable backup at inside linebacker, then things went wrong.
Last season, rookie Stevenson Sylvester was the special teams' standout, and Pittsburgh brought back Larry Foote to be the primary backup for a lot of money.
With these two in place, it is time to let Sylvester get a bigger role on the team by allowing Fox to walk.
In addition to the presence of Sylvester and Foote, Fox took some terrible penalties last season, particularly an awful personal foul near the end of the Super Bowl. That alone made many want to cut him on the spot.
