A couple of points from Bobby:
REWARDED: The players who made an impact from the bench against Exeter Chiefs have clearly got their reward with five of them making the starting XV. It's a bold move to do so, but let us remember, for the best part of an hour, Wasps were pretty average against Exeter Chiefs
KNOCK ON EFFECT: What the changes do mean is Wasps have an even stronger bench than last week. All three front-row replacements bring dynamism, Fifita and Barbeary are serious weapons to hold in reserve while Porter, Mills and Watson all bring real quality.
