He's reluctant to workout against other top PGs:

As if the lottery landscape wasn't unpredictable already, Brandon Knight might be muddying these waters even more than before.

While it remains likely that Cleveland will take Duke point guard Kyrie Irving at the top spot and (insert team name here, since Minnesota continues to spread the word that it would like to move down) will take Arizona's Derrick Williams at No. 2, sources say the Kentucky point guard could be risking his chance to go third overall to Utah by refusing to work out against competition. Knight has an open invitation to join Connecticut's Kemba Walker, BYU's Jimmer Fredette and UCLA's Malcolm Lee in a June 15 workout with the Jazz, but sources close to both sides said he has yet to decide whether to take part.
What's more, there are rumblings that Utah is less than thrilled at the notion that Knight would even consider dictating the terms with the No. 3 pick (although Turkish center Enes Kanter already did just that in his Jazz workout in Chicago in which Toronto also took part). It's unclear whether the Jazz would take a hard-line stance and refuse to take Knight unless he worked out against other top-line competitors, but that appears to be a possibility.

I attended Knight's workout in Sacramento on June 2 and walked away convinced that Knight saw the Kings as his so-called first-round floor at No. 7. The problem there, predictably, is that the one-on-none approach wasn't well received by the Kings' brass either. As if separating the talent in this crop wasn't tough enough, Knight's tactic appears to have thrown a subtle wildcard into the process.
