Caldwell is the beneficiary of inheriting a great team with maybe the best QB to ever play. We will find out how good he is this season. I don't think he is aware there is a game going on most of the time.
Blinkie has made some very poor decisions in crucial games. 1) Super Bowl - go for a 51 yrd field goal when your kicker hasn't even attempted one that long in the past 5 yrs, 2) Jacksonville last year - call time out when Jags perfectly content to run out the clock and play for overtime, 3) Jets Playoff game - call time out with under 30 sec to play when the Jets are content to try a 40+ yard field goal.
Everyone makes mistakes but as far as I am aware, he still thinks none of those calls was wrong.
