Tank Abbott is this guy a skilled fighter ... No just a strong guy who can punch and in his heyday he silenced a lot of critics... He dominated a lot of mma "fighters" by purely being strong and being able to brawl.
Do you think they could give him a pair of boding gloves and put him in a boxing ring and tell him to go dominate a world class heavyweight.... Boxer 
A lot of you are living in denial
Do you really think that being "strong" and "able to brawl" is enough to be a successful MMA fighter

That's exactly what Kimbo Slice was. The "badass street fighter" that would kill all the "mma guys". Yet, he was utterly embarrassed when he give it his all in MMA.
And, even though Kimbo sucked that bad, he still managed to beat piss out of Tank Abbot (see link below). Speaking of Tank, not sure why you keep bringing him up. He was a complete embarrassment to MMA. Just so you know, his record is 10 wins and 14 losses. None of the wins that he has, are over any notable opponents. Get this, most of the no-name fighters he beat, have more losses on their records than they do wins. One guy has 7 wins and 20 losses...lol. Another guy, 0 wins and 5 losses.
Tank is exactly what you're talking about Meso, a no skill brawler. And, that is why he failed so miserably against skilled MMA fighters.
Here is clip of Tank, in his prime, getting dominated by a "no skill mma guy". Tank begs for the ref to stop the fight...lol.
