Again, Honestly, I hope we don't roll in to the whole "if he is looking at the NBA he shouldn't go" mind set that many of us have around this time of the year. I don't think David Johnson has any regrets, nor does the other JUCO who went straight the NBA. Nor does D. Mitchell whom NOBODY thought should leave.
Honestly, if you take a step back and review his body of work, Ellis falls into that Dame Lillard role. At 6'3" he can get his own shot off, he is uber athletic and highly skilled. He can score at all levels.C ertain things are easy in the NBA if you are on a decent team. Look at his numbers... they are directly comparable to Russ Smith and Donovan Mitchell's numbers...
He will probably get a guaranteed contract, maybe a 2-way deal as an undrafted free agent, but honestly, I think he goes late in the 2nd round as an "Under the Radar" guard. Will depend on his combine numbers.
