The two running backs, who are represented by the same agency, met during a Super Bowl LI party back in 2017 and roomed together during their first offseason in Green Bay.

When you pull back the layers, however, Jones feels he clicked so well with Williams because his jovial and gregarious nature reminds him quite a bit of his twin brother, Alvin Jr.

There's a competitive side of that friendship, too. It's not just always fun and games with Williams. In practice this week, Williams got on Jones after he jogged back from a run instead of finishing to the end zone like the two did on their previous carries.

In two-plus seasons together, Jones and Williams have combined for 4,296 total yards and 42 touchdowns.

"Jamaal's one of my favorite teammates, man," receiver Davante Adams said. "He's what you need and really want in a teammate on a team like this – especially when you have a great running back who was drafted the same year as him. The unselfishness, and you can see how they vibe with each other, it's kind of, it gives me chills sometimes when I look at them on the field because they have so much fun together and really relish and love each other's success."

That energy translates to the football field, as well. Even when the Packers were trailing late against the Los Angeles Chargers on Nov. 3, Williams stayed on his feet through the first would-be tackler on a screen pass to extend for seven yards and a first down on second-and-5.

While sharing the backfield with Jones, Williams is still having a career year with personal bests in average rushing yards (4.5), receiving touchdowns (five) and a career-long carry of 45 yards against Detroit last month.
