I'd like to see the team start Bayless in Game 2 with Miller. I agree with Barkley on one thing: Nash couldn't handle Miller, so they had to switch him off Miller. So have Bayless play the lion's share of minutes and let Nash chase Bayless him around all game. Nash isn't going to be able to keep Bayless in front of him and trying will sap some of his energy.
Fernandez just doesn't have any one tool that he can rely on. In some sense, he's a broken-play superstar...when things are chaotic and the defense isn't set, he has space to shoot, pass and get to the rim. He can do it all. But against set, halfcourt defenses, there's nothing he can do except shoot when open and hope he's hot.
Bayless currently doesn't have a diverse game, but he can often get into the paint and score or draw fouls. One weapon is better than no weapons. And attacking the hoop is something you can't ever have too much of in playoff games, where referees seem to disproportionately reward "being aggressive."
