Shooting, passing, floor vision, poise, BB IQ, decision making and hesitation moves should separate Burke from these guys. Burke's challenge will be getting to the rim and finishing in the lane.
People always talk about players' elite quickness, but the reality is that players play at game speed, not at a full sprint.
I looked up at their college stats (last year of play) and at first glance Augustin's & Flynn's stats are very similar to Burke. For assists Burke is at 6.7 this year, Augustin was 5.8 and Flynn's was 6.7. FG percentages were 47.9%, 43.9% and 46%. 3pt percentages were 40%, 38%, 32%. Burke is slightly better in passing/floor vision (assists), shooting (FG% and 3pt%), but not by a great margin.
One stat that stood out the most was Assist/Turnover Ratio, Burke is at 3.3, Augustin 2.1 and Flynn 2. This does support the view that Burke is better at decision making (he's able to produce high assists pg, while keeping TO to a minimum).
Offensive rating (points produced through FGs, FTs, Assist, ORB, per possession) - Burke is at 124, Augustin 116 and Flynn 112. So Burke is clearly better when taken all the offensive stats into account.
