I think he'll get his ovation but not to the degree that some of Boston's more recent rivals have. I don't think Kobe Bryant joins the ranks of Derek Jeter, Magic Johnson, or Peyton Manning as the one athlete Boston sports fans loved to hate year after year. Jeter, Magic, and Manning were constantly obstacles that the Boston teams had to fight tenaciously to get to the next level. I mean yeah we saw Celtics-Lakers in the finals a few years ago, but that rivalry lasted 3 years and then never came close to happening again. Jeter's Yankees, Magic's Lakers, and Mannings Colts/Broncos lasted for a long time.
Not to say I don't respect Kobe and his legacy. I just don't think he's made that kind of impact in Boston that the other ones have.
