#2 No storylines in the pipeline for The Viking Raiders

Week in, week out the RAW Tag Team Champions keep on facing enhancement talent when teams like The Street Profits have simply nothing to do. It just doesn't make any sense, does it? The Viking Raiders have not faced enough credible opponents and their popularity is decreasing every week, due to the bad booking.
The Viking Raiders need a good showing and for that, they will need a feud, which WWE seemingly doesn't have. If The Viking Raiders are not involved at TLC, that will reduce the value of the RAW Tag Team Championships in the eyes of the WWE Universe.

#1 Brock Lesnar might not be involved at TLC at all

Brock Lesnar hasn't shown up on RAW since Survivor Series and that clearly hints at The Beast Incarnate not being involved at TLC in any capacity or else WWE would have had a new challenger ready for him.
This is what the WWE Universe doesn't like about Lesnar as one can be forgiven to think that there's only one prestigious championship on RAW and that is the United States Championship. Nevertheless, we at least know that Lesnar will be involved at Royal Rumble.
