You have to hand it to Le’Veon Bell — and Ben Roethlisberger did that in one form or another 23 times Sunday — that when he’s healthy, when he’s not suspended, he is the NFL’s best running back.

And, according to one veteran Steelers starter, he might be better than ever.

Miss the first three games and all those practices for skipping drug tests? Rehabbing a torn up knee since November? He was as rusty as a Ferrari Spider back on the track after a short hiatus.

Bell averaged a mere 6.5 yards per carry in the first half of the Steelers’ whirlwind, 43-14 barbecue of the Kansas City Chiefs Sunday. That warm-up contained just six carries for 39 yards. He then went out and ticked off 105 yards on 12 carries in the second half.

His total: 144 yards rushing, an 8-yard average per carry and five receptions for another 34 yards.

Guard Ramon Foster, out with a chest injury, nevertheless saw something from the sideline in Bell he had not seen in his previous three years. Bell always was praised for his patience in waiting for a hole to open, picking it and hitting it.

“To me, it looks like he was more straight ahead,” said Foster, who added that’s a good thing. “Him in between tackles, his burst of speed, there wasn’t any hesitation in it. I thought he looked like a different guy.

“Now he’s one-cutting and going. Some of those runs, he was that close to being a house call. I think he switched it up a little bit, whether he wants to admit it or not. That may be just the growth of his game.”

Bell did not want to admit it.

“I don’t feel like I did. I felt I was out there just trying to find holes and do what I could. Sometimes, I feel like it was there so I have to take it, there’s no need to set up anything. The offensive line did a great job of opening up holes, so I took what I got.”

Whether his running style is evolving into something different/better, the Steelers leaned on his versatility as a receiver more Sunday night.

Bell lined up in the backfield, in the slot, in motion and split out wide like Antonio Brown. The poor Chiefs did not know where he was going, or how to stop him.

“You know, it’s hard because you treat him as a running back,” coach Mike Tomlin said. “You treat him as a wide receiver and that’s kind of what we wanted to do. He is a weapon wherever we put him. So we wanted to move him around and do some stuff, and I thought we could have even used him more in the passing game.”
