The Portland Trail Blazers worked out six more prospects, including Gonzaga's Kelly Olynyk, at the Tualatin practice facility on Tuesday morning in advance of the 2013 NBA Draft.

Blazers owner Paul Allen was not in attendance according to Joe Freeman of The Oregonian on Twitter. Allen did attend workouts for Georgia's Kentavious Caldwell-Pope, Indiana's Cody Zeller and Lehigh's C.J. McCollum.

Murphy's added size and strength has helped him do a better job establishing post position and battling with the opposition inside on both ends of the floor, though it hasn't been without negative side effects. While Murphy remains a relatively agile player for a big man, he definitely seems to have lost some of his fluidity over the years, not being able to change directions as well, looking a little more awkward in his movements, and often finding himself falling to the floor following lay-up attempts on offense or closeouts on defense. Given how sizeable a transformation he's made in such a short time period, he probably hasn't yet found the ideal combination of size and speed for his body, but he's clearly shown the work ethic and drive to maximize his physical abilities, and likely will continue to do so going forward. On the offensive end, Murphy's undergone a similar transformation over the years with his role in Florida's offense, evolving from a garbage-man type inside player in his first two seasons to much more of an outside shooting specialist the past two years.

What makes Olynyk unique is his versatility and skill level for a 7-footer. By no means a flashy scorer and far from a freak athlete, the inside-outside threat can use his size and soft touch to score in the post, finish his opportunities at the rim, and step out and make shots from the perimeter. ... With that said, scouts will have significantly more pressing questions about his rebounding ability and defensive presence. Lacking the explosiveness to rebound outside of his area or provide a presence blocking shots from the weakside, Olynyk does not make a sizeable contribution in either area relative to his peers, ranking last and fifth to last in blocks and defensive rebounds per-40 minutes pace adjusted respectively among the centers in our top-100. He does a solid job crashing the offensive glass, but must work to become a bigger factor on the defensive end. Olynyk shows somewhat inconsistent intensity on the defensive end, though he does operate in a decent stance and moves his feet well for his size. His lack of lateral quickness and often poor awareness limit his impact on this end of the floor. He'll need to improve his intensity and show better focus to help make up for his shortcomings as best he can on this end of the floor.

Stephens actually may be the best athlete in the 2013 draft, but few know what exactly he has to offer an NBA team. That's because he played a majority of his minutes at the power forward or center position in college, even though at 6'5 and 188-pounds, he looks more the part of an NBA shooting guard than even a prototypical small forward. While he is extremely undersized, he is incredibly explosive both in transition and from a standstill, and displays the requisite quickness for virtually any position in the NBA.

Olynyk was linked to the Blazers in a mock draft back in April.

The Blazers opened the pre-draft process by working out six players two Thursdays back, another four two Fridays back, six more last Monday and another six last Friday morning. They also put Indiana's Cody Zeller through an individual workout on Friday afternoon and Lehigh's C.J. McCollum got the same treatment on Monday. Blazers GM Neil Olshey took questions about the pre-draft process and Blazers coach Terry Stotts explained his role in the workouts.

The Blazers are expected to run a total of nine or 10 workouts in advance of the 2013 NBA Draft, set for June 27. The Blazers hold the No. 10 pick in the first round and three second-round picks (No. 39, 40 and 45).
