Tarik Cohen

The Bears used Tarik Cohen at running back, outside receiver and in the slot last season and weren’t shy about adding new formations and personnel groupings to his game-week workload. He was a quick study, they said, and he became perhaps their most dangerous offensive weapon.

In retrospect, however, Nagy said the Bears might have taxed Cohen’s preparation too much down the stretch.

‘‘We moved [Cohen] around a lot last year, and I do feel like there was a time — probably later in the season — where we probably gave him a little bit too much,’’ Nagy said before practice Tuesday. ‘‘And when you mentally drain them, it pulls them back physically.’’

Tarik Cohen's touches may go down to keep him fresh, but they're much more likely to go down due to the team adding three pass-catching backs in David Montgomery, Mike Davis, and Cordarrelle Patterson and also getting Anthony Miller back healthy. Cohen looks like he will see fewer carries and targets, capping his upside on a team that will keep games low-scoring due to a strong defense.
