WWE announced that Corey Graves will be JBL's replacement on SmackDown Live, but he'll be pulling double duty by also remaining as color commentator on Raw. This will bring about changes to 205 Live and Main Event with Nigel McGuinness taking Graves' spot on those two shows while still doing NXT.
This is a VERY good sign. While it would have been cool for someone like Renee to get a chance, Graves working both brands' commentating teams shows how highly they think of him. Maybe he will go on to become the main announcer. Goodness knows Cole was never good in that role. Still sad to see JBL go as he did offer that heel perspective that's needed froom commentators. Still, this is definitely a good idea on WWE's part. I'm happy for Nigel's new opportunity as well even though I don't watch 205 Live.
