In the day of the information super-highway, you can scour the internet for expert opinions.
That being said, I have never seen *one* expert opinion, be it sports-writer, player, ex-player, coach, ex-coach... who has produced
a list of greatest NBA players of all time that includes Kobe in the top 5.
Until I see even one reputable list that has Kobe in the top 5, I'll state definitively that yes, it is a stretch.
No offense, but you show a clear lack of knowledge in NBA history.
You don't even include Oscar Robertson in your top 10, a guy who AVERAGED a triple double for an entire season, and almost averaged a triple double for 4 straight seasons.
