The term hybrid AWPer is misleading.
I prefer to say that there are primary AWPers and secondary AWPers. Some primary AWPers are highly skilled and can use other weapons that require more mechanical precision, whereas others are far more dependent on the AWP to have any sort of impact.
Secondary AWPers are the true hybrids, with prime Olof and Coldzera being the most obvious examples. They weren't the primary AWPers for their teams, yet they still picked it up occasionally when it made sense to do so and had a lot of impact with it.
ZywOo and Dev1ce were unquestionably the primary AWPers for their teams in 2019. They will almost always choose the AWP when it's available to them, just like kennyS or Jame. They're just much better at getting kills with other weapons during rounds where they don't have access to the AWP. That shouldn't invalidate their status as AWPers.
With all that said, the reality is that when CS:GO is finally done and people start looking at the all-time greatest players, there is a very high likelihood that the top 5 could be made up enitrely of primary AWPers... which is ridiculous when primary AWPers are outnumbered 4 to 1 (1 per team usually).
