LeGarrette Blount on his way out with Pittsburgh Steelers

NASHVILLE, Tenn. -- The Pittsburgh Steelers-LeGarrette Blount union is not going to end well.

The only question after Blount reportedly left the field before the end of the Steelers' 27-24 win against the Tennessee Titans is whether it ends sooner rather than later.

Blount couldn't be bothered to stick around for a win that Le'Veon Bell, his best friend on the team, helped deliver because he didn't receive one carry Monday night at LP Field.

The selfish act screamed the kind of me-first attitude that may explain why Blount is with his fourth team in five NFL seasons even though he is averaging 4.6 yards per carry for his career.

Cutting ties with Blount, who picked up an early strike with the Steelers in August when he and Bell were charged with misdemeanor possession of marijuana, would easily be addition by subtraction.

The Steelers probably would love nothing more than to get Blount as far away from Bell as possible -- and to jettison the kind of attitude that might poison younger players.

Releasing Blount, who signed a two-year, $3.85 million deal last March, wouldn't put the Steelers in a tough place from a salary-cap standpoint because they only guaranteed his $975,000 signing bonus. If the Steelers release Blount before the end of this season or in the offseason he will count just $475,000 against their 2015 salary cap.

That is a pittance.

The problem with the math when it comes to cutting Blount before the end of this season is the Steelers simply don't have many bodies -- or options -- at running back.

Rookie Dri Archer is the No. 3 back behind Bell and Blount and the scatback has played so sparingly that he is averaging just over one carry per game.

Bell, as he showed in his trucking of the Titans, is fully capable of handling a full workload. And the second-year man gets a bye week to rest up before the Steelers play their final five games of the regular season.

But if Bell were to go down for an injury for an extended period of time and the Steelers had only Archer in reserve -- and whatever back they signed off the street if they released Blount -- the season might go with him.

The short-term risk may just be worth it in the long run considering the message it would send.

But it is probably not one the Steelers are willing to take just yet because they are 7-4 and just percentage points out of first place in the AFC North.

Blount, however, can probably count on some terse words from coach Mike Tomlin, a fine of some sort and maybe even a suspension unless he has some plausible explanation for why he left the field early.

Tomlin also can point out that even though Blount's days in Pittsburgh are probably numbered, he better be on his best behavior the rest of the season.

Blount, after all, is going to have to convince yet another team to take a chance on him. The only question is when that time will come.
