What is ironic about the very end of the novel? Why do you think the author chooses to end the story that way?

The ending of the novel Hoops is ironic because the very thing that serves as Lonnie's deliverance also ends up being Cal's doom. There is also irony in the fact that basketball, which had once been such a singular focus for both men, later serves as a source of growth. For Lonnie, it allows him to see beyond his own selfish desire to become famous and leave his humble beginnings, and it shows him how rewarding it can be to truly be part of a team. In Cal's case, he learns from Lonnie's struggles and realizes that there is no shame in wanting a better life, even if it means great sacrifice. Even though Cal loses his life at the end, there is a certain satisfaction that goes with knowing he died having done the right thing.
