Even the most positive assessment of Kasparas Jakucionis' initial foray into NBA basketball would have to be tempered with a tinge of caution, if not disappointment. Jakucionis, the No. 20 overall pick in the NBA Draft, slid to Miami for a reason: His physical package (notably, his overall athleticism) was somewhat limiting, and his penchant for turnovers gradually grew from concerning to alarming.

And Jakucionis, a Big Ten All-Freshman team selection in last season's one-and-done campaign at Illinois, did little to dispel certain doubts about his three-point shot – which may have been hampered by a midseason forearm injury but, frankly, wasn't a consistent weapon at any time in his freshman season in Champaign.

In fact, Jakucionis shot a cringey 31.8 percent from the field across six games this summer, and his assist-to-turnover rate of 0.68-to-1 was an outright disaster. Yet he showed improvement from the California Classic to the greater NBA Summer League schedule, his solid defense was a surprise, and his competitiveness and resilience impressed the Miami Heat front office. His 24-point (including seven threes), four-assist, two-turnover gem against Atlanta should be proof enough of the franchise's optimism.

Realistically, the jump from Division I to the NBA (even Summer League competition) was bound to be an adjustment for Jakucionis – as was playing off the ball more frequently, which has been the case this summer. His development may unspool across a longer arc than most other players who had been projected for the NBA Draft lottery, but he's at least in the right place in Miami to see it through.
