Eh I think his target should be 6-10 rushes per game. If he sees an opening for a good gain on early downs he should always take it.
Not all QBs are rhythm QBs and I think the offense needs to account for it.
If I'm Monti, I'm building a team that can play great defense and always run the ball. Make Kyler the icing on the cake, not the 100% focus of the offense. The Rams game is a perfect example of how not to call a game with Kyler Murray. The Cardinals should never have a game where Conner only gets 6 carries. The game got away when Petzing got impatient and started throwing constantly. Murray hasn't shown the ability lately to carry this team.
