The Lions need to do whatever it takes to end up with ILB Rey Maulagua and DT B.J. Raji. Maulagua #1 and trade up a few spots if need be to land Raji. Duke Robinson in the 2nd now that would be a great draft.
I like your mentality and positions, just not the specific players. Curry is the LB at #1, not Maualuga. Curry has the complete game, is roughly the same size as Rey, and is faster to boot. Maualuga is only good against the run between the tackles. Misdirection runs and pass plays will be a problem.
Duke Robinson is a great choice for #33. My preference there too.
I think you get a solid, block eating DT in Raji's teammate, Ron Brace two rounds later at #65. They both go roughly 330 lbs, IIRC. This opens up the #20 pick. You can get a solid LT, or whatever you prefer here. I'm pretty open to the possibilities with this pick. I'm sold on Curry, Robinson, and Brace though. If Brace played another year without Raji, we'd be talking about him in the top 20 IMO. For now though, he's a steal in the 3rd.
#1 Trade down and grab Curry
We couldn't trade down very far and still get Curry. 2 or 3 spots at most. That would be a good move if we get one more 3rd rounder or something similar IMO.
