It's a great draft for defensive talent. I have 174 players with 5th RD or better grades, and 94 are defensive players.
Takk is interesting. I don't like him as much as you do, but he's in my top 75 overall, so I do think that he'll be a good player. I agree that he could potentially play DE, OLB/Edge, or Off OLB. He has traits that you like for each - speed, length, tenacity/motor. I'm not sure what to expect from him as a pass rusher, though. With his motor, he should grab some clean-up sacks, but his lack of refinement aside (and we definitely have to try to contextualize the shoulder within that), he performed poorly on the jumps and agility drills. It's very possible that the shoulder hampered those performances, but watching him, I thought the tests matched the tape - very fast but not sudden. He's similar to Dante Fowler - just lighter. Fowler went #3 overall. I didn't like it, but Takk will clearly have traits that NFL teams covet. I love watching him. He's as relentless as any player in the draft. With that speed, I do think he has a shot of making it work, but I think he must improve his upper body strength significantly (maybe just the shoulder), and I'm a little worried about how far back his shoulder will set him.
I think Watt and Bowser are the guys at OLB/Edge in this class. They have the rare tools you only see once every 2-3 years. With Watt, the main concern is his knees. With Bowser, I don't think you have any major concerns, but you have less evidence from him that he can play up to his talent. After them, I like Rivers. He has a lot of the same traits - just on a lesser level. But, he is stronger and faster than either, and he was much more productive than either. Rivers is probably a poor fit for Miami, but I'd still consider him at 54.
This is a really weird draft, because Safety and TE are usually very thin groups, and by their standards, they're overflowing with talent this year. I have 11 Safeties in my top 100 - not including Baker and D. King, who I have at Slot. And, after the top 100, there are waves of more solid Safeties.
Appreciate all the quality posts, CK! The board is much better when you're around.
