To my mind, let's say - for sake of argument - we cheated.
We broke a rule by sending an intern to hang out by a tree with a pair of binocculars.
If sending someone to watch a training session is cheating, then we may have cheated.
I'm now more interested in proportionate punishment in this scenario.
Diving for a penalty is cheating. Failing a drugs test is cheating.
When are we going to replay the 1986 World Cup quarter final against Argentina? Maradona clearly cheated.
The question is (if guilty) "to what extent did your cheating give you an advantage?". The punishment needs to be proportionate to that.
If cheating in and of itself means expulsion from a competition, we are expelling vast numbers of clubs from huge numbers of competitions.
It's hard to see - on any basis - how watching Boro's training gave us more than a 0.00001% edge. If that's enough to get you expelled from the play-offs, then anyone who dives for a penalty kick in the Football League should immediately see their club kicked into a Beazer's Home League regional divisions.
