"Now, let's talk about what Bell does not do on the field.
He does not break open games. His longest carry in 15 games this season went for 27 yards, and he had just three runs of more than 20 yards. Among the league’s top backs, only Indianapolis’ 34-year-old Frank Gore had a shorter season-long run, and 26 backs had more runs of 20-plus yards.
Although it is often said Bell possesses receiver skills so exceptional he could operate as an extra wideout, he rarely functions in that role. His receptions consisted primarily of check-downs by Ben Roethlisberger and produced an average gain of 7.7 yards. Among backs who caught at least 50 passes, that figure tied for eighth place.
Most damning, though, is that Bell does not impose his will upon the defense. He averaged 4.0 yards per carry in 2017, tied for 10th among the league’s top 15 rushers. He carried 321 times, and fully 15 percent of those attempts went for no gain or negative yardage. Add in those that produced fewer than 3 yards — and subtract his three 1-yard touchdowns and six converted first downs — and the share of failed runs rises to 39 percent."
