I deliberately didn't bold Rusev's name because SD already has a monster heel that could be used in a prominent role if used right: Baron Corbin.
I don't know about Zayn being the next D Bry, but he's the epitome of an underdog. Maybe down the road I could see it, but I don't see Zayn in the main title picture if drafted. However, I totally see him contending for the IC title or in matches right before the main event.
As for Cesaro, I feel for this dude. For awhile, he's been critical of WWE's booking overall and for good reason. Now, Vince has some strange grudge against wrestlers who have either criticized him or was part of a different wrestling company (TNA, ROH, WCW, ECW, etc.) so I wonder if Cesaro will stay on RAW for the rest of his career. Vince HAS to know SD would be a much better fit for him so I could see him making sure Cesaro suffers. Such a shame.
