People who think Barrett is doomed by holding the Intercontinental Title should have some hope, and this is why:
Barrett has been on RAW every week since his return to the ring. He is constantly given the mic, and has been spotlighted greatly, even at the Hall of Fame ceremony. When's the last time Big E got the mic? Would it have been the first? I wouldn't buy into this whole idea Barrett is doomed, he will get his spotlight.
Now, as far as title defenses, why not? He had a nice 10 minute match with Big E, with a cool finish and great crowd response. Did Big E ever get these kind of reactions? I was at Survivor Series for Big E vs. Axel, to say the crowd was snoozing was an understatement, in fact, they were the whole show... but that's a complete other story.
Barrett seems like he's gonna be given the green light with this gimmick and now it is up to him to make it work. If he disappears off of WWE TV and is relegated to Superstars and Main Event, then it is time to start complaining about higher-ups and how they view their lower-tier (and apparently second-tier) championship.
