Well, except it is. You can post that he has "devastating power" all you want, but he hasn't actually shown that he has devastating power at the top level, nor that he's smart enough for Fury at this point. What he showed against Stiverne was a decent jab and straight right; he's hardly showing that his strengths are Fury's weaknesses. It's a bit ludicrous to think Wilder is going to have spent years just fighting non-entities, beat Stiverne and then start beating up on some of the top five heavyweights in the world. Even if I accepted that his power was all that - and I don't - he doesn't have the seasoning.
If he were to fight three or four times in 2015 against different opponents to try to progress and learn? Sure, a Fury fight in 2016 is reasonable. But if he were to fight him now he'd actually be an underdog for a good reason - he hasn't got the experience, hasn't beaten anyone as good as Fury, hasn't faced a live body of Fury's size and talents, and hasn't knocked out anyone at that level.
Fury is a very risky fight for Wilder. Even putting aside the in-ring stuff, if he loses, what then? He loses not just his title but any notoriety he gained by beating Stiverne. Why? Because he spent years fighting non-entities - whilst focusing on learning in the gym - and then lost in his second step up. He'd be better served building himself up with title defences and continuing to learn. From a promotional standpoint it builds up interest in any eventual fight with Fury, and it also gives him a softer cushion to fall back on should he lose.
