Lewis has taken 98 offensive snaps out of 560, 17.5%. His low count is 7 (3 different weeks); his high count is 22 in week 6.

His special teams snaps have been in the 4 - 8 per game range.
Lewis was brought in at $2.1 mil for 1 year to in-line run block and chip in on special teams. He's here because of Graham's poor blocking. He has not been a productive receiver for many years. You could say he's had only one better than mediocre receiving year in his career.
Last season with Jacksonville he had a 79% snap count with 24 catches on 48 targets for a 50% catch rate and 318 yards. The 5 TDs provided receiving value in the red zone. Jacksonville was a run heavy team, or what stands for one today, but they still passed the ball half the time with 527 attempts, with Lewis having little to show for it, despite the high snap count, other than the TDs. And you would not expect him to be a TE red zone target with Graham around. And that was his best receiving year since 2013 by a narrow margin.
While we might have expected him to sneak out for more than 1 catch on 2 targets from a run look, he was never going to be more than the minor factor in the passing game. I thought they might use him as the lead back (that job went to Kendricks), but given those sets call for an in-line TE he's out there doing that job.
The Graham and Lewis value propositions, for this year anyway, need to be looked at in combination.
