In college and high school, having wider hashmarks has a pretty good impact on the play of the game- it’s another variable that has to be taken into account.
IIRC the rules, if the play ends with the ball between the hashmarks, it’s lined up where it was down. If it’s outside the hashmarks when the play ends, it’s put on the nearest hashmark. So there’s a variation from play to play where the ball will be in play. You may be out on the hashmarks or you may be dead-center. This means that your offense has to adjust to where the ball is, and so does the defense- if you’re on one or the other, the wide side of the field is larger and harder to cover for the defense, but the short side is a lot harder to run/pass into as well.
The pros OTOH, have much narrower hashmarks which minimize the issues of starting the play on either hashmark. This is just one of many rule changes in the pros that seem to be intended to ease the burden on the offense- another is the different clock rules w.r.t. run plays, etc…
I think if the hashmarks were moved out, you’d see it as one more consideration for the offense when choosing a play, but in general teams would play just like they do already. After all, college and high school teams don’t do a whole lot of that kind of thing, and their hashmarks are considerably wider than the pros are.
