Brian mentioned how many options the O has for the TE (the scrape counterpunch, the fake scrape counterpunch that freed Koger up for that 20 yard rumbling pitch/catch), etc. Totally agree.
The use of the TE is probably my favorite development of the O so far, and I'd also include (1) the WRs' hands (we all know Matthews' has been able to catch anything thrown his way since he got here, but the lack of drops on basic passes has been a fantastic surprise) - we'll see how this holds up in sub-60 weather in a month or so, (2) the blitz pickups/blocking in general by the RBs - Minor in particular. I counted at least 5 crushing blocks by Minor in the ND game and Brian highlighted at least 2 key blocks (the pancake on the 3rd down conversion to Odoms on the last drive, and the block on the GW TD pass), (3) Brown's hands out of the backfield - that guy looks silky smooth flaring out into the flat, into space. We know he has the speed - the issue with him has been breaking through tackles and making something happen when the hole isn't big enough for a truck. Love to see the staff figuring out other ways for him to get into space, though I do hope to see him do it with carries out of the backfield.
One more quick thought - Forcier's STUDBOLT! run looked to be a "fake counterpunch" (as Brian described - when Koger pulls but instead of blowing up the DE, avoids him and heads for the flat)... ND apparently tried to take that away by rolling McCarthy (?) forward leaving nothing but empty space.
I hope to see teams try to take away that TE flex play because with Tate/Denard running it and needing only to beat a DE, I'll take that all season. Can you freaking imagine having a crucial 4th down play turn on Threet or (no offense, young man) Sheridan having to beat the DE to get into space? Night and day.
