Kobe was, hands down, the best player in the NBA for the 2005, 2006, 2007, 2008, 2009, and 2010 seasons.
I'll argue 2003 as well.
Seven MVP's sounds ridiculous, but then again, Michael Jordan was the best player in the NBA for nearly his entire career.
They wouldn't want to change the award to reflect the best player in the league, though, because at that point, you're not featuring many players over the last few decades.
I'd argue 2003 as well, Kobe was tearing the record books for really the first time in his career and was easily the most complete player in the entire league. It was hard to swallow because the same player that won it the year before won it again. I never understood how a player could win this award two years in a row with basically the same type of year and not reward the dude tearing up the record books (it happened in 2006 too!). I think you're reaching a bit with the 2005 season, injuries and a completely new scene made things tough but you can't be the best player in the game
