Man, I really love what Raheem Morris is doing to challenge offensive pass pro schemes.
With the TE not attached, he can't be in a true pass pro - a chip and release, at best. So, he walks up Upton Stout to the left with Warner mugging the B-gap and Keione White the left of the center. So, if the line wants a "big on big" blocking where the RB won't have to try and block a DE off the opposite side, they have to have a 4-man slide to Stout's side. Otherwise, Stout blitzing through the B-gap(between guard and tackle) would put the RB on the DE. So, this isolates Fred Warner on the RB in pass pro.
Perfect example of a coach "putting his players in a position to succeed". It's a common phrase, but this is what it looks like.
