I was watching a bunch of games this weekend with my wife.
I casually said that it is interesting how some teams are smart, and others just dumb.
It's not that every player is intelligent, but key players are and their decision making rubs off on others.
The Rams have become a smart team. The smartest team year after year is probably the Pats. But the Rams are getting there.
Some teams, like the Bucs, are dumb. Cincy is dumb. The Browns are dumb. Watch them and various players will make the most forehead slapping decisions at the worst possible moments.
You are right; clearly Gurley is a smart player who makes really good decisions. And you see the same thing happening in Goff (in fact, I saw a segment on some sports show that more or less said that of all the NFC QBs, which one is likely to make the best decisions during the game during the playoffs. 2 of the 3 said Goff, the 3rd said Keenum).
And as I recall, Snead said that McVay emphasizes intelligence as a high priority in selecting players.
