Re: Do you think Kobe could've won a championship
The '07 team? If that's the team you're talking about, there isn't a player in NBA history that could have led that particular team to a title. Not prime Shaq, not prime Jordan, not current LeBron, and certainly no form of Kobe.
That team was horrible. Larry Hughes missed the finals, that seems to be often overlooked. Besides if it wasn't for some miracle Boobie Gibson 3's, and a LeBron James massacre of Detroit in GM5, the Cavs don't even make the finals. Hell Kobe likely wouldn't have been able to get that team out of the first round. When he had comparable talent to that team he pouted, and his team got put out in the first round.
If you mean '10, then maybe. We don't know what would have happened if LeBron hadn't quit. In 2009 there's no shot. In order for the Cavs to win Kobe would have had to have at least a 43/8/8 series, as LeBron had a 38/8/8 one. Considering the numbers Kobe put up against those same Magic in the finals, I think it's safe to say we wouldn't see those numbers from Kobe.
