And with Kevin Durant and Jeff Green as the focal points of the offense, Westbrook must also learn to find his own opportunities while effectively getting Durant and Green enough touches.
In projecting Westbrook's rookie season stats, perhaps the most logical player for comparison is Williams, Utah's No. 3 overall pick in 2005.
Williams averaged 10.8 points and 4.5 rebounds in 28.8 minutes as a rookie alongside Carlos Boozer, Andrei Kirilenko and Mehmet Okur. He played 80 games, 47 as a starter while splitting time with Keith McLeod and Milt Palacio.
For as good as Williams has become, even he struggled with the complexity of the position in his first season.
But Carlesimo is high on Westbrook and is entering Tuesday's training camp with confidence in his rookie.
While fans are likely to fall in love with Westbrook's high-flying dunks, Carlesimo likes what he calls Westbrook's "fundamental game,” defined by his stellar defense, stout work ethic and strong confidence.
"That alone is going to get him playing time, both at point guard and shooting guard,” Carlesimo said.
But don't expect gaudy numbers.
