The offense will miss Diggs’ explosiveness
I think it’s unlikely the Vikings will be able to 100% replace Diggs’ production with just one wide receiver.
Diggs had some versatility. The Vikings occasionally drew up a jet sweep for him, and sometimes he would even try to throw the ball out of it. It wasn’t exactly the crux of the Vikings’ offense, but plays like that force opposing teams to have to prepare for one more thing in practice that week.
I think Harvin has a similar versatility. He can line up in the backfield. He was also solid at getting the ball in space and making plays when he was with Minnesota.
Harvin might not be what he used to be, but he could still add value to the Vikings — whether that be in the passing game, on unique play calls or in the return game. I think with the way the offseason looks right now, the Vikings could use Harvin, especially after Diggs’ departure.
