In most instances, I would line up in the wishbone and call the triple option to the wide side of the field or the strong side of the formation.
I like the wishbone as a goal line formation. And I have always wondered why more people don't use it in goal line situations- whether a team has a drop back passer or an option QB. I am glad that Dan Mullen agrees with me and that we use it. I could not believe that a MSU coach would do something different and it was cool to see that something that I always thought would work does work. It was kind of like thinking about a song, and then the song that you were thinking about comes on the radio. I like the fact that it increases your options on the goal line without really having to sacrifice beef up front. In a traditional goal line set, it's pretty much the QB straight forward, or a running back straight ahead most of the time, and the defense usually has a pretty good idea of where the ball is going to go and who is going to get the ball. With the wishbone, you put two halfbacks back there, and they don't know who is going to get the ball, who is going to be lead blocking, if the TE is going to go out for a pass, if the QB is going to sneak it, if it's going to be an option play, or if the fullback is going to get it.
Now, if it's the fourth quarter and there are under 30 seconds, I'm going to call a run- pass option play to the right side of the formation- assuming a right handed QB with the TE going to the corner of the end zone and a WR/TE running some type of crossing route from the left side of the field to the right side of the field so that if the TE is covered, the QB has a second option , and if neither of those are there and he thinks that he can run it in, run for it, and if they defend it well, throw it away, and come back for fourth down.
On fourth down, I would go shotgun, five wide with four WR's to one side of the formation and the X on the other side, and have the X run a slant, and if they have him doubled on that side ( I think a slant would still probably work), I would call a screen to the side where the four WR's are to Chad Bumphis and let him work his magic.
If I'm Les Miles, I spike it on fourth down.
