I understand that asthma is a serious health issue.
However, some wrestlers who get boo'd have seemingly used the asthma issue to get a break at very key times of matches.
I have seen some matches against a certain asthmatic wrestler go over 14 minutes for just 3 periods of wrestling because of stoppages and stalling tactics like unhooking headgear and taking it off and slowly putting it back on. Coming EXTREMELY slowly back to the center of the mat on restarts, slowly adjusting knee pads.... all these things add huge amounts of time for a match. Worse, it seems to be a behavior learned and used by other non asthmatic teammates of a certain team in particular.
Referees need to keep the time strictly limited to injury time only and NOT allow delaying and stalling tactics that are used in this manner.
There are many wrestlers whose endurance is a key part of how they win a match... by exhausting their opponent.
IMO these stoppages put the wrestler who is conditioned for endurance at a severe disadvantage to wrestlers who continually get a break to recover, abuses the rules (calling for blood time when not bleeding) and use stalling tactics.
It might also be argued that the use of an inhaler and the drug boost could possibly give the asthmatic wrestler a short term advantage by allowing their body, for a short time, to absorb more oxygen then their opponent.
If a wrestler cannot finish a match without the use of a drug to continue then they should forfeit the match.
