Diggs already admitted earlier this off-season that he needs to take care of his body better. He said soft tissue injuries are avoidable and it is something he is going to address with his training this year.
It's exciting to think about what a healthy, explosive Stefon Diggs would look like for an entire season... 90+ catches, 1,100+ yards, and 5-7 TDs... ? I hope we get to see it.
