I was looking around to see if Marial Shayok was mentioned in any mock drafts in the 2nd round and the answer seems to be "no". I saw an aggregate of 6 or 7 mocks and he didn't get one listing. During the season, I was thinking he might be a 2nd-round guy who ends up in the G League. Look at Nader's production his senior year compared to Shayok's (or at least that was my logic). I guess they felt Nader had a higher ceiling. I found a concise summary of Shayok's pros and cons from nbascoutinglive.com. Here's his summary:
Pros:
Good shooter, especially from deep
Fairly good scorer off the dribble
Excels at scoring on off-ball motion plays
Very good free throw shooter
Adequate playmaker
Decent defender
Better athlete than advertised
Cons:
Lacks an elite first step off the dribble
Can be prone to hoisting up questionable shots
Needs to improve his rebounding
Can struggle to guard quicker players
Late bloomer
Old for a draft prospect, may have limited upside
Summary:
After having three nondescript seasons at Virginia, Marial Shayok elected to transfer to Iowa State, and he is now having a breakout season as a senior. Shayok is a very good shooter that can make shots from all over the floor, and he is averaging nearly 19 points per game.
There are some concerns, though. He's only had one year of significant production and his advanced age may suggest that he may not have nearly as much upside as some of the other prospects in this draft, but Shayok is a skilled shooter that could excel as a floor spacer for an NBA team at the next level.
