You've got a solid point about the lack of fight camp, but the whole "he's a featherweight!" bullshit really falls apart once you get into the specifics.
Per Volk's own words over the last year or two, the guy weighs 170 or so in the cage (he used to weigh in the high 160s earlier in his UFC career), while Islam usually has a cage weight of no more than 175 , and sometimes reported aa in the lower 170s.
Volk is an average LW by cage weight mass, and a MASSIVE featherweight. Good for him, he's an amazing weight cutter (which is a skill and physical ability that varies greatly between fighters).
Whining about a difference of 2 - 5 lbs is hilarious, since that's fucking standard in any fight between people in the same weight class. When you say "but Volk is a featherweight!", those that's the cage weight difference you're making such a big deal about. Lol
