These days most call your "DT" a "DE." It's what Cam Jordan and Tyson Alualu played when they were here, and they are prototypes in terms of size, 270-290 lbs. What you call DE/OLB is usually referred to as OLB these days. Your terminology sounds like the old Oklahoma 52, which is basically a 3-4.
And your third row, I think you meant ILB, obviously.
Correct, this is a 5-2 defense and was common 20+ years ago. The 3-4 has the DE replaced with an OLB, who will play upright (usually, even if they move up on the line) and usually more off the ball unless his side is covered by a TE. It puts the same number of guys (5 - DE, NT, DE, ILB, ILB) in position inside the tackles to stop the run as a 5-2 (5 - DT, NT, DT, ILB, ILB), but adds the versatility to hide blitz packages better and cover guys in the passing game that was hard to do with the 5-2 and a dedicated pass-rushing DE on the outside.
Ex-player Chris McCain makes for an excellent OLB in the 3-4 defense, as to who would be ideal in size/athleticism for that position, and I agree that a 275-290 lb DE with athleticism (fast hands, good movement in his hips to get around guys..) and a 290-350 lb NT with strength to require double teams is ideal in the 3-4. Maybe we don't have those guys on the current roster, with one or two exceptions, but we could probably get by with the guys we have in the DE/NT positions until we can recruit for the system.
