The failure of not scoring a touchdown on first and goal from the three yard line has nothing do with execution. This has been an ongoing problem for many years that has cost many games. The odds of success especially against competition that is equal or better than you diminishes greatly with the formation that we continue to use. No wide outs so you have 22 players bunched up within 30 feet of each other. There is no room to run. Put 4 recievers out and then run, it reduces congestion by 36%. Put 5 out and call for the quarterback to pick a hole and run.
