I've never seen the guy play, nor do I have time to do another scouting report, but one guy who seems to be shooting up draftexpress' mock draft is Hassan Whiteside.
If you think Jarvis Varnado is an impressive shotblocker with 5 blocks in 30 minutes, Whiteside is averaging a mammoth 5.5 in 25! The guy is also averaging 9 boards, so per 40 you have 14 boards and 8.5 blocks.
"Standing 6’11 with excellent length and great athleticism, Whiteside is an extremely intriguing physical prospect, theoretically having the tools to effectively multiple positions at the next level. Since the first time we saw him a little over a year ago at a prep tournament, he’s added some weight to his frame, but still could stand to add significant lower and upper body strength in the near future, both of which could help his game substantially."
The guy seems to be a bit raw on the offensive end, so not someone you'd take top 5, but as it is, we project to end up closer to 10th than we do 3rd (which more than likely is where Cousins will be taken). It's noted that he's not only a great off ball defender due to timing, but also has great lateral quickness, something you very rarely see in 6'11" players.
The guy looks like an impressive prospect, who's willing to adopt him? I've got a big organic chemistry exam in a week so I won't be seeing too much daylight.
