Duke is averaging an ACC leading 7.1 per carry between the tackles...
Lots of yards in zone plays come from cutbacks between the tackles. Between the tackles doesn't mean it's a power, counter or lead, etc.
Well, there are zone plays and then there are stretch zone plays. I am also not a fan of the stretch plays.
It gives the defender too much time to cut off angles and pursue. As chise mentions, sure, we might be able to break off a couple decent long runs from it but overall, it results in negative plays more often than not.
In theory it sounds right, but reality contradicts what both of you are saying. I watched every single offensive play from the Wake Forest game. There was one negative play off of what I presume you're calling "stretch zone." It just so happened to be a play that should be thrown out of the playbook: stretch zone with Hagens actually (!) leading. Both times we ran it on Saturday, it was awkward and quickly stopped.
In the first half, Duke ran 8 zone stretch plays versus 2 non-zone (and, yet, these were slow developing misdirection/counter plays). He averaged 4 yards/carry on zone stretch with no negative plays. He averaged 3 yards/carry with no negative plays on non-zone, but again, these were slow developing counters.
In the second half, Duke ran 7 zone stretch plays versus 13 non-zone (there was a small sprinkle of quick hitters - 3 if I charted correctly - but mostly were slower developing counter and misdirection plays). He averaged 4.7 yards/carry on zone stretch. He averaged 6.7 on non-zone (remember: the bulk being very slow developing outside counter plays).
Looking into the numbers and what I charted, nearly 70% of Duke's carries were on outside counters/misdirections or zone stretch plays. 7 out of 8 of his longest runs of the day were either zone stretch or plays that required him to use counter steps + have Walford come from the other side of the formation in misdirection.
Pretty clear that the coaches not only see Duke's best weapon as the cutback, they call plays that fit it. We
are blessed that he's a great RB who's capable of running inside to keep the defense honest on straight powers and leads. On the other hand, there's a pretty obvious tendency to try Crawford on the powers and leads. Crawford had over 70% of his yards come on the plays you're asking for and only averaged 3 yards/carry on outside stretch zone plays.
* FWIW, saw some other tendencies that are really positive for us against FSU.
** Also, forgive if I mischarted a handful of plays. I just did this in 30 minutes on my lunch break. The general idea and numbers should be solid.
