Dream oozes charisma whenever he comes out to deliver a promo or wrestle a match. With him already being extremely popular, Triple H hasn't brought him up to the main roster yet, and this is a praiseworthy decision on The Game's part.
Instead of taking a risk with calling him up during Vince McMahon's reign, Triple H should wait it out and do it when he takes over. One can't even begin to imagine what The Velveteen Dream could achieve on the main roster, with his mentor being with him at all times to support and guide him.
