Chris Bosh was often referred to as the most important player for the Miami Heat over the last four seasons, something that probably not many people understood. With LeBron James gone to Cleveland and Dwyane Wade - while arguably still the key to how far Miami goes - no longer the elite scorer he once was, the Heat are asking Bosh for more than ever. So far, he's delivering, with 77 points in Miami's first three games and flourishing again in the go-to-option role that he had for his seven seasons in Toronto. ''I feel like I am a much better player and a much better leader,'' said Bosh, announced Monday as the NBA's Eastern Conference player of the week.
