Jeremy Woo of Sports Illustrated reports Saturday that Cliff Alexander, the Kansas power forward who may very well be the best of the undrafted players from this draft, has signed with the Nets for summer league.

More on Cliff Alexander: he'll be with the Nets for summer league. Brooklyn could have interest in keeping him beyond that. — Jeremy Woo (@Jeremy_Woo) June 27, 2015

Alexander was seen at the Nets training facility last week, but did not work out.

Saturday afternoon, Alexander seemed to confirm it, retweeting a message from a Chicago hoops blogger saying he had signed with Brooklyn.

On Monday, Mike Mazzeo tweeted that Alexander joined the summer league team after looking at various options.

Alexander, a 6'9" power forward with a 7'4" wingspan and a controversial past, went undrafted Thursday, a year after being seen as one of the top two or three recruits in the country. His freshman year at Kansas ended with him losing eligibility after the NCAA claimed that he had received illegal funds from a financial firm.

Here's how SB Nation described his fall from grace Friday...

Alexander's fall is maybe the most precipitous in the entire draft. He was projected as a lottery pick before ever reaching Kansas, where he was supposed to team with first-rounder Kelly Oubre to make Bill Self's Jayhawks dangerous in 2014-15. But Alexander never broke into Self's starting lineup to stay, and then an NCAA investigation into his amateur status prematurely ended his Kansas career. With that cloud over him and a less than thrilling season of play on his record, Alexander's stock was damaged entering the pre-draft process -- but few thought he would go entirely undrafted. He's still got a big body and the talent to be an NBA player, but Alexander's NBA career now must run through undrafted free agency.

The Nets will pay in two summer leagues, the Orlando league in Central Florida starting July 4, then the NBA Summer League in Las Vegas a week later. Among those expected to play are: draft picks Rondae Hollis-Jefferson and Juan Pablo Vaulet as well as returning Nets Markel Brown, Cory Jefferson and 2014 pick Xavier Thames.

After going undrafted, Alexander tweeted this...
