When watching film on the Pats, the issue of run/pass balance came out in the difference between halves. New England was 26th league-wide in first-half runs called, 14th in the second half. These run/pass ratios are exactly the theories that went into building the West-Coast Offense, but despite a common misperception, the Patriots run a modern variant on the Erhardt-Perkins system. Their approach is less smash-mouth. It uses the pass more. However, since Erhardt is reputed to have said, “Pass to score, run to win”, the McDaniels version of this approach (which was originally installed by Charlie Weis and has morphed and adapted to changes in personnel often since) uses the pass more in the first half and runs more in the second.
