To say former running back LeSean McCoy is not Eric Bieniemy's biggest fan is probably the understatement of the century.
The Kansas City Chiefs' offensive coordinator has returned to training camp following a recent absence due to a personal matter.
It did not take long for Bieniemy to assert himself during practice on Monday, with Kenneth Walker feeling his wrath.
Former Chiefs running back McCoy has long-standing beef with Bieniemy, with 'Shady' McCoy claiming the offensive coordinator did not play a role in the Chiefs' successful passing game during his first stint.
McCoy also suggested the Chiefs would rehire Bieniemy earlier this year for his 'discipline and yelling', with the recent video of the OC on social media making McCoy feel vindicated.

Chiefs fans loved hearing Bieniemy get after Walker , who has shown a real lack of discipline in recent weeks of training camp.
Bieniemy has returned to camp and put his foot down, but McCoy has been mocking the footage of the Chiefs' OC.
After seeing the footage on Instagram, McCoy simply responded with four laughing face emojis.
It was back in January when McCoy claimed Bieniemy would be brought back this offseason for his discipline and yelling'.
Months on and it is clear to see the former Chiefs running back already feels as if his point has been proven correct.
McCoy won a Super Bowl whilst Bieniemy was the offensive coordinator in Kansas City, but it is apparent there is very little appreciation for his time under the 56-year-old.
Aside from his final year, which was with the Tampa Bay Buccaneers, McCoy's single season with the Chiefs was his worst on record.
With Bieniemy his OC, McCoy only produced 465 yards, which would suggest why the former running back does not look back on his time under the Chiefs' coach so fondly.
