There is a difference between getting picked every week for Ajax or Celtic compared to NAC or Hibs. Culina and Rogic being first team players is a much better confirmation of their quality compared to starting at smaller clubs. They have a lot more quality and competition within the squads, style of play is different as they are expected to win, they have continental football every year.
I considered the best players in Aliga to be around the equivalent of those European leagues (outside the really big clubs). This is a pool of probably 20 odd players. These guys go to the mid tier european leagues and do well (Balard, Nisbet, Triantis, O'Neill, Bos etc), while others come back home and do the same (Borello, Teague, Leckie, Thomas).
If we subbed out Arzani, Tilio, Velupillay for Balard, Irankunda and Nisbet I think the squad is slightly better, but it isn't changing the game. The problem I have is less about the individual selection arguments, and more about the unwarranted outrage. Because the outrage has consumed most of the discussion rather than anything interesting / useful about the different qualities players bring, experience of the squad, structure etc.
The squad has 5 players with 0 caps and 16 players with less than 15 caps. There are only 6 guys who have more than 30 caps (this feels very low historically). On paper he looks to be trying to bring through a new generation. To the point where, with only 6 veterans, I am worried about about the level of experience going into must win qualifiers. But I don't think I have seen this talked about anywhere, and it seems a lot of that is to do with the outrage over 2 or 3 selections / general dislike of Popa.
