Would the playbook still work if I used Coach Pop and a '98 Spurs playbook or Luke Walton and an '87 Lakers playbook, or is it just limited to current teams?
And one last thing I'd add to your list, is to play the game at a pace YOU'RE comfortable with. I got rattled in my 2nd play through of Ruby league starting 0-4, but rallied to win 8 straight, and then rallied to win 5 straight in amethyst league after starting 4-3 using pretty much your methods.
