I feel where Jimbo is coming from if you outright say I feel I can beat a particular Coach then you should be Man enough to play that Coach. FREEZE
Now is that Ego or Substance.

Ego-Being boastful about your ability, why Boast if you can play that will Be visably seen.

Wanting to play a coach for personal reasons, record, trophy or to attempt to embarrass another coach at home or abroad

Running up the score to prove you are superior

Challenging a coach rudely in a style you have no knowledge of just to play a rival, nine times out of ten your gonna get wiiizzzzaxxxxed!

Substance-Wanting to Challenge a coach because you want to test your skill against his in a fair enjoyable competition filled environment.

Playing in a new style home or abroad out of interest of being an ambassador to the hobby and to expose and expand ones knowledge of EF/MF

Having respect for a coach when he is beaten out of a game to then be a teacher and help at that moment to make that coach aware of things he could do better next time, helping not gloating

To understand new champs are born and Old champs are still here, but on any level big or small A Champ is a Champ.

Ego or Substance, ill take the Substance.

Stay Blessed
