The Lions are seeking additional depth to their linebacking corps, so the hope here is that Harold will be able to crack Detroit's final 53-man roster prior to Week 1 of the 2018 regular season. If yes, he will add a little more pass rush to the Lions defense.

The 49ers appear happy with merely parting ways with Harold here, as the club is expected to insert Dekoda Watson into Harold's former strong side linebacker spot. The draft pick might be of little consequence here, so San Francisco simply wanted Harold gone.

Harold might become a decent source for sacks in 2018, but first he must actually make the Lions this preseason. He is too risky to draft in IDP leagues at this point.
