The Suns added another SF to their roster in former Harvard star Kyle Casey, according to Paul Coro. Casey went undrafted in the 2014 NBA Draft after helping Harvard to their first ever Ivy League title in 2011. He played for Helios Suns Domzale in the Slovenia-Telemach League last year. Apparently, there is some sort of connection between "Suns" and the beautiful nation of Slovenia, even after the departure from Phoenix of the Dragić brothers.
Casey profiles as a decent scorer, but not much of a 3-point threat. He hit only 31% of his 3s in college and 29% for his Slovenian team last year. Draft Express reports he measured 6'7.5", 227 lbs with a 7'1" wingspan at his pre-draft workout, so has nice size for a SF, and could potentially play PF in small ball lineups. He played small ball center as a senior at Harvard, when he averaged 10.1 rebounds per 40 minutes.
Unfortunately, Casey may be best known for being named in an academic cheating scandal at Harvard. These things happen in the NCAA, but it's noteworthy to have occurred at an Ivy League school as prestigious as Harvard. Casey worked hard to redeem himself, and returned to the team in 2013-14 after withdrawing from school for a year due to fallout from the scandal. He doesn't seem to be a character problem, just a kid who made a mistake.
No need to read too much into this signing. Casey will be a training camp player who's signed only for camp and preseason, and unlikely to make the final Suns roster. He might end up as a D-League prospect in Bakersfield.
It's not easy finding footage of a player from Harvard and the Slovenian League, so excuse the Zapruder Film quality of this video. Looks like Casey's got a little athleticism.
