HoopsHype's Jorge Sierra reports that Nick Minnerath, McCallum's Detroit teammate, will play with Sacramento. Minnerath is a 6'9 big man scorer who can shoot the three.
C.J. Aiken will also join the Kings at Summer League, reports CSNPhilly.com. Also a 6'9 big man, Aiken spent his last two years at St. Joseph's, where he was an excellent shotblocker (2.6 per game) for his size.
Finally, Iowa State wing Will Clyburn will play for the Kings reports CycloneFantatic.com's Chris Williams. Clyburn averaged 15 points, 7 rebounds and 2 assists per game for ISU last season.
It'll be interesting to see whether Jimmer Fredette or Isaiah Thomas, both going into their third years, are asked to play in Vegas.
