Some snippets from the article below and it's debatable and to me it's debatable if he was healthy enough to receive more touches but without a doubt sounds like injuries plagued him all season:
Swift said he plans to meet with "a couple doctors" about his injuries in the coming weeks, but is operating under the assumption 
he will return to full health with time off.
Swift suffered a high ankle sprain in the first half of the Lions' season-opening loss to the Philadelphia Eagles, then 
separated his left shoulder two weeks later in a loss to the Minnesota Vikings
But he said he still was bothered by a shoulder injury that limited what he could do in the weight room all year.
"It was kind of just pushing through it," he said. "I feel like I was at a standstill with it, just had to make it work the best way I could."
As for his offseason plans, Swift said he'll be back working out once his body heals and he gets the all-clear from doctors with an eye on being more consistently productive in 2023.
"I play a violent game and I know that, but things I can’t control is things I can’t control," he said. "All I can do is respond and I feel like I did that. With the cards I was dealt early on, playing through a high ankle 
and the whole season with a separated shoulder, just doing what I can week in and week out, like I said, I’m blessed to be able to do that but get time off, get back, reset, let everything heal up and just come back ready to go."
