If a guy you are cornering is obviously using one game, and you are trying to get him to switch his game in the middle - thats not a good corner.
A good corner doesnt yell out general information like "Work harder," "submit him," etc. A good corner should be telling you exactly what to do. Granted, Cameron wasnt that general. However, when the guy you are cornering is obviously trying to play a closed guard game you help him play that game.
You dont yell "Go to butterfly" a hundred times and hope all of a sudden he hears you. You say things like "Break his posture, and control his wrists. Set up your sub by doing x,y and z." etc.
Matt Serra, for example, was a great corner. Tito also. They gave solid advice, detailed advice, and step by step directions. Cameron was like BJ yelling "omoplata!" from every position possible lol. You need to give the guy a blueprint on how to get there.
Most importantly, though, you need to work with the guy. After telling the guy to go to butterfly 87329 times, and he doesnt, you should realize that for some reason he doesnt want to go there. Help him play the game he chose. In the end, no matter what, hes the one thats inside. I 100% believe that with better coaching, Tim submits JT in the first or early in the second round.
But when you are trying to work closed guard and your corner keeps yelling "butterfly" and thats it, thats not a good corner.
