That's already the game plan until the other team takes a 2 score lead in the 2nd half and then you have to largely abandon the run.

That being said, you do have to keep defenses on their toes by throwing on 1st or 2nd down occasionally even if your QB is what Blake is. Fournette is great about getting an extra yard or two that other backs wouldn't get, but you can't be playing to get to 3rd and short every series because you aren't going to convert 3rd downs at 75% or probably even at 50% consistently. Jags are currently ranked 21st in the league with a 36% 3rd down conversion rate. It's going to have to be a lot better than that combined with fewer turnovers for this team to win more games than it loses or we'll need to somehow manufacture more big plays. Running on 1st and 2nd and passing on 3rd is predictable and won't likely lead to many big plays.
