Kevin Durant's concern about what he might be when he returns from his Achilles injury reportedly crystallized his desire to have a star by his side, according to Ric Bucher of Bleacher Report. Durant and Kyrie Irving agreed to four-year deals with the Brooklyn Nets instead of the New York Knicks.

Durant was open to playing for the Knicks, but Irving was set on joining the Nets, the team he grew up rooting for while growing up in New Jersey. KD wasn't going to join the Knicks by himself.

Sources who had conversations with Durant after the Achilles injury, meanwhile, say his concern about what he might be when he returns crystallized his desire to have another bona fide star by his side.The Knicks might have been able to accommodate that even without signing Kyrie, if not for the Draft Lottery.

Achilles injuries are the toughest ailments to come back from in sports. Even though Kevin Durant doesn't rely on his athleticism like Russell Westbrook or Derrick Rose back in the day, it's still fair to wonder if the two-time Finals MVP is going to be the same player in 2020-21 when he comes back.

That's why Durant wanted to join a team this offseason with another superstar and he got his wish with Kyrie Irving. The Nets can't wait for the 2020-21 season when Durant will be back on the floor with Irving.
