When the sequel kicks off next year, Kraglin will not be very happy with Yondu (Michael Rooker) or the Guardians as a whole.
If the friendship between Kraglin and Yondu is starting to break already, Yondu joining the Guardians as a team member will certainly not help that cause.
It is entirely possible that Kraglin expresses his concerns about Yondu’s leadership to Flanagan’s character, which then results in Yondu leaving the group.
One of the unsung heroes was Sean Gunn, the younger brother of the director, who played Kraglin in the movie, though he also did motion capture for Rocket.
