Thirteen NBA owners included in Forbes rich list

Thirteen owners of NBA franchises have been included in Forbes' list of the 400 richest Americans.

At the top of the list in terms of the association is Portland Trail Blazers and Microsoft co-founder Paul Allen, who is worth $15.8 billion.

Elsewhere, Micky Arison (Miami Heat, $5.9 billion), Stan Kroenke (Denver Nuggets, $5.3 billion) and Charles Dolan (New York Knicks, $3.3 billion) all make the list too.

Brooklyn Nets owner Mikhail Prokhorov would have been second only to Allen, but as the list is solely based on Americans he is omitted.
