2 or 3 games out of 16 is not consistently blowing leads. How many of those games did not feature points off turnovers from the opposition? Please answer that. A football game is the sum of the entire game, not one drive near the end. Turnovers & 3 and outs put the defense on the field longer than they should be and as a result they are worn out by the end. You HAVE to factor in turnovers.
it absolutely is, 2-3 is an incredible amount. Let's check how many times they were in a situation like that and came through. 2009: vs. NE vs. Buf(at Toronto) failed 3 times, succeed 2 times, 40% success rate. 2010: at Miami(though they blew a double digit lead and nearly blew the game) Minnesota(though the blew a double digit lead and nearly blew the game) at Pitt(though they nearly blew the game) 3 success, 3 fail. 50% 2011: Dal 1 success, 3 failures, 25% 2012: Arizona Tennessee 2 success, 2 failures. 50% total: 11 failures, 8 success. 42% an elite D should be closer to 80%
