I talked about this in the Ballard's draft post. It's definitely the defining decision of this year's draft. You could have picked the exact same players EXCEPT stayed at 26 and picking Sweat instead of getting 49 (and a 2 next year) and picking Banogu.
It's interesting. NFL.com did combine breakdown of the most athletic players and Sweat and Banogu tied at 99. Sweat was faster, but Sweat was more explosive in other areas.
Here's what I think watching the video game clips of both guys. Sweat is first and foremost a pass rusher --- a "going forward" guy. I think that Banogu is much more athletic moving backward and side to side. Ballard hinted that this was a consideration when he said they're toying with the idea of moving Banogu all around, at SAM, at Mike, as a pass rusher.
I think he's much more of a chess piece than Sweat.
But Sweat could be a double-digit sack guy down the road. That's what this draft could be defined by years from now.
