We should always recruit elite athletes like Seth Green. We can find a spot for freak athletes.
As to Slab's point, it is noted, but it's also important to keep in mind that they built the system for Seth Green. This is one of PJ's greatest strengths (IMO), he has a system but he is 100% comfortable adjusting it to personnel. If we can recruit athletes like Seth, sign them up and put them somewhere. Seth's athleticism could allow him to play wildcat QB (which is essentially RB), WR, TE, he has the size and speed to play DE and possibly even safety in certain packages.
Adding to my point about PJ's ability to adapt to personnel, I think we'll see that with Spann-Ford. I was dead wrong, I thought they'd move him to DE because PJ usually doesn't use the TEs much. So I thought it would be a bit of a waste to have such a high caliber athlete essentially being a sixth OL.
