There is one word that sums up Derrick Williams – athleticism.

If you didn’t watch all 10 minutes of that highlight reel, stop reading and watch the dunkfest now. Keep in mind, that’s a compilation of throw-downs from just last year.

The Knicks signed the athletic wing to a 2 year, $10 million contract. The second year is a player option.

The former 2nd overall pick, in the 2011 draft, has been a disappointment so far in his career. To make matters worse, he was drafted ahead of elite NBA wings such as Klay Thompson, Kawhi Leonard and Jimmy Butler.

Williams has suffered from tweener syndrome, not quite settling into either forward position. He’s not big enough to play the 4, and not quick or skilled enough to play the 3. However, he is starting to establish himself as a valuable role player in the NBA. Williams’ versatility actually improves lineup diversity, given his ability to play in big or small lineups.

At 24 years old, there is still time for the talented wing. The slate is there, he just needs to develop his skill level. Williams, blessed with good athleticism for his size, is a menace around the rim and in transition. If he can develop a consistent outside shot, he’ll be a more dangerous offensive threat.

Williams will be a shot in the arm for the anemic Knicks. New York was sorely lacking athleticism and energy from their bench last year. At the very least, expect him to contribute 15-20 energy minutes a night from either forward spot.

Jackson has given second-year coach Derek Fisher a new toy to play with. Williams has the size and athleticism to make a bigger impact than he currently does. Fisher will have an opportunity to coach the 24-year old to his potential.
