Who would you take at #9 in this scenario

There are going to be awkward fits moving to a 3-4 & it will take a couple years to get there. Can't really have them both as 3-4 OLB's either because while they are athletic for 4-3 DE's they do not have the athleticism to both be a 3-4 OLB (you can have one of them be a straight up stand up edge rusher but not both, at least long term). Need someone more athletic on the opposite side unless Staley wants to run a 5-2 defense.
Granderson came into the league as a small speed rusher with size suited more for 3-4. During his combine his athleticism was rated average-67 just under the Good-70 threshold. That was amongst DE/edges rather than all rushers including 3-4 according to the category on the NFL website.

He only bulked up to fit Allen’s plodder type of DE mold. He can essentially trim back down 7 pounds to his original draft weight for more advantage as a standup rusher.

I can’t really see them drafting OLB at #9 because of Granderson’s athleticism questions in the 3-4. He’s proven to be a very effective rusher regardless of the scheme change. He can’t be traded before June because of the 20.4M dead money charge. He has a tradeable cap hit after 6/1 but don’t think it’s ideal to use a top 10 pick on a starting spot thats not weak. 2nd-3rd round seems to fit OLB depth range.
