DE Jonathan Greenard, Florida
Watching Greenard play football is exhausting. His motor helps make up for his 6-3, 263-pound frame. Still, he moves very well and sets the edge against the run about as well as he gets after the quarterback. If the 49ers are aiming to replace Armstead, being good at both is essential. Greenard is a more natural edge rusher than Armstead though and may not have the size to kick inside. Still, he’d give the 49ers a much-needed depth piece on the edge that can be on the field for all three downs. He’s even more valuable if he can play multiple spots along the line. Ideally the 49ers won’t have to add an edge defender early, but it’s a reality that they could easily face if they’re unable to get Armstead signed to a long-term deal.
