I am always happy when we try to improve ourselves. I cant imagine this being much different than what we did in 04, the ONLY QB we've ever had that I think DC or PF trusted enough to run a true NH wore 16 and left 10 years ago.
It may not wear us out, but anyone who says our Oline will react the same to being in a 2 point stance for the duration of the play clock as they do if they were standing relaxed in the huddle is just incorrect. It may not be much, but it will be there, and over the duration of a game, it will show up.
It will be tougger on the Dline due to them being in the 3 point. So all in all it is good for us.
