for PR, it doesn't matter that much then.
for Docter, I thought taping injury is better than massage because he makes a player continue to play the game even if there is a little injury. As for GS, basically I rotate the players between games, so it wouldn't help that much in my first impression, but today my 2 players play over 90 minutes within 2 games. I might have to change my mind.
for salary cap issue, I still be in debt in weekly net income, but it seems I can get some profits by expanding arena and ticket price change within a few weeks. Thanks for your advice.
