I'm Italian and here in Europe and UK you hardly hear about this A level rubbish.
Is it something you guys get from American football?
For example in football (aka soccer) we never talk about A level athletes, we talk about players being skilled. It is packed with extremely athletic guys who can't make it in football because they are not skilled enough and do not have the talent to become skilled.
On here I always hear how these supposedly A level athletes would roast all UFC FIGHTERS. I think it's utter bulls hit. Being a great fighter requires not only athleticism but also (and more importantly) a huge set of skills, a solid chin and huge huge guts.
Let's have a look at the current champs:
HW
C not very athletic but great skill and chin
LHW: since DC is HW let's say it s Jones, B level athlete with great distance control and timing, length, supersolid chin
MW: BOBBY Knuckles, very well rounded, wouldn't say he s an extraordinary athlete
Ww: Woodley is a very gifted, blacksplosive athlete....A level confirmed
LW: khabib , not a level, huge skill and chin
It' getting late so I ll stop here
