Mike Knox is a potentially brilliant wrestler, and I'm suprised that nobody has voiced this already. Look at him, he is a big burly guy with a pretty unique look thanks to his beard and that is often enough when it comes to making main event heels. Seriously, already he's better than Matt Morgan, but there's so much more.
In the ring, he's not world class, but he's certainly better than, say, Abyss. However, this isn't what should make him a must attain for anyone that owns a wrestling company, it is his voice and calm demeanour. Seriously, people are slating that aspect of his character, but a softly spoken man that's actually a monster is a hugely intimidating person, just look at Mike Tyson. The way Knox should be booked is as an intelligent, and softly spoken, but fundamentally twisted sociopath. Book him like that and you have a genuinely intimidating heel.
I don't for one second believe that TNA or indeed any current wrestling promotion has that sort of vision for Knox, and he'd ultimately go the way of all big heels wherever he went, which is a crying shame. Knox shouldn't go to TNA unless they were going to utilise his full potential, which I doubt they would.
