Maybe, but in the past, I've seen a 5-4 point guard lead the country in assists & assists per game for the Lady Zips.
And I've coached someone that wasn't even 5 feet. She was one of our program's most important players to winning a conference title and winning 20 games in a row two years ago at the varsity H.S. level. There are obvious limitations, but can also be an advantage in other areas.
I think they will be most impactful on the defensive end. They're closer to the floor, so they're going to have a better chance for steals, deflections, and/or just making the ball-handler's day miserable. I believe the strength of this team will be the post players, particularly with Bass & Riley.
