Well, the Bruce Irvin is a mixed example because they aren't using him as a DE anymore, but I get your point. They try different things.
As can be said for every draftee, none have played a meaningful down in the NFL. Of course. And I agree with you on some of your points.
I disagree with you on how some of you evaluate Michael Sam. Now, I grant you, I do my evaluations in a very unconventional manner. But... those allowed me to hit on guys like Alshon Jeffery when all I heard was he was a fat prima donna who would be the next Mike Williams. So, when I evaluate Michael Sam, it's through my own unconventional lens. As for the LDE deal, he can only line up where the Rams line him up. He did play RDE plenty against Miami, for example, but because it was only that one game, it didn't balance out the other 3 games of mostly LDE. That's not to say that they wouldn't have played him at RDE, but there are only so many snaps a game. The question is what does he do with those snaps? I actually saw him play the run BETTER from the RDE position than from the LDE, yet he pass rushed better from LDE. That's probably a relic from Mizzou where he rarely swapped with Ealy.
So, I have to grant that when we talk about him, we may be looking at different things or seeing the same things, but applying grossly differing weights to them. And I can't really say that there's a right or wrong to that. I just know that I've had a fair bit of success with my own concoction.
I don't know what to say about Special Teams. Almost no DEs play special teams and when the Rams graded him, they took NONE of his special teams play into account. Which meant that he lost those 13 pounds... for nothing or worse it might have cost him a job.
Lastly, I really do hear you when you talk about scheme and that he's a bit raw (we differ on the degree of raw, but...he's a rookie so he's gonna be raw). I just don't believe that Michael Sam wouldn't have been better than Cassius Marsh or a host of other players. I just don't. I think Ethan Westbrooks is an anomaly and the Rams got a steal, but he's certainly not typical of the talent found in UDFAs. I think Ethan Westbrooks is a 2nd round talent that got washed out by Div II bias, inconsistent production and penalty-itis. However, once he got to the Rams, it seems he was all cured and played up to his potential. Michael Sam was about a 3rd round talent given the depth of this draft and seems to have played to that. So, I'm not surprised that Ethan Westbrooks outplayed him.
I guess the thing that bothers me is this. Presuming that even though it was no secret at Mizzou... had they really just told Michael Sam to just stay in the closet until after the draft and he kept his mouth shut and for whatever reason, no one outed him... I honestly can't see a reason for him going outside of the 5th round, even if folks dinged him HARD because of the Combine and totally ignored his Pro Day.
Now here's the thing. If he goes in the 5th round... are we having this discussion? Or is he ON a 53 for some team and THEN he announces and we wonder...would it have changed anything? Cuz, the lesson to any gay college athlete NOW is to shut your damn mouth, get drafted and then, if you want to come out, do it after your first game as a pro when it's too late to be cut.
