How long will each match be at SummerSlam?

#9 Raw Women's Championship: Alexa Bliss (c) vs. Ronda Rousey (~11 minutes)

This will go longer than it needs to.

In truth, this match shouldn't and doesn't need to go longer than 5-6 minutes. Alexa Bliss should cower for a little while and then get demolished by Ronda Rousey.

Unfortunately, as we've already seen with her three matches with Nia Jax, WWE won't be too keen on giving Alexa Bliss the decisive comeuppance she's avoided for nearly two years. We can expect her to take control for some of the match and cause it to drag before Ronda Rousey makes her comeback. How it ends from there is anyone's guess.
