Read Option is a play, not an offense. It can be a way to run the ball out of shotgun, because the read option is run out of shotgun. But it's not a way of life, not and offense, not the basis for an offense, or anything to worry about.
Not to quibble, but you could base an offense off of read option, and I don't know that I'd call it a "play" because there are any number of read option plays that you can run, Power, dive, counter, trap, veer, inverted veer, yada, yada, yada.
