Since you just won't let the Watkins thing die:
1) DT's are not usually measured by sacks but by tackles and TFL's. NT's usually by controlling both A gaps. Sacks are less part of a DT measurement than a DE or Edge Rush OLB. But clearly a DT that can bring you a few sacks each year is a valuable thing. Suh played 3 technique most of his career so that allowed him more opportunities for sacks. With the Rams, it will be less so.
2) What else are you going to rate a WR on other than receptions, total yards, and TD's? You seem to want to rate Watkins equally on blocks and decoys.
3) The decoy argument as applied to Tavon Austin also falls on deaf ears. So why does it only to apply to Sammy Watkins as a WR?
4) The issue this story about is only about sacks; not tying up Olinemen or QB pressures or run stuffing. And that is a conventional DT/NT primary job.
5) Sammy Watkins was/is a fine WR. Most of us here wanted to keep him even at a pretty high salary. The Rams put a top end number value on him, which is what any organization ought to do. He got an offer well over that number. McVay clearly values what Cooks brings to the game at the X position more than what Watkins brings to it under his schemes. If you want to tell McVay he's wrong about it, fine. Snead and McVay have said Cooks is the ideal fit but Sammy wasn't, and they did it about as diplomatically but clearly as possible while avoiding in any way insulting Watkins.
