The Giants’ pool of possible coaches to replace Tom Coughlin was short on pizazz from the beginning. Half the candidates were brainy tacticians in headsets, a football equivalent of Sheldon from “The Big Bang Theory.”
Most of the rest were solid, unexciting middle-aged guys with head coaching backgrounds but who nonetheless had some kind of blemish as an N.F.L. leader.
Then there was Ben McAdoo, the Giants’ offensive coordinator for the last two years. The team officially named him as its new head coach Thursday afternoon. There is some mystery about what kind of head coach the 38-year-old McAdoo will be because he has never been a head coach in high school, college or pro football.
