As much as football meant to him, as much as it mattered to win, those things only counted for Ali if he was also staying true to Allah.
I think Freedman utilizes this sentence to really emphasize that although the line between work and play can be often blurred, at the end of the day, there is a fine line that exists that differentiates the two. This usually places one, priority-wise, above the other. In this case, play is referring to Ali playing football for his school team and with his friends. This responsibility is clearly one that Ali views with a lot of pride. In this case, "work" is referring to Ali's personal religious duties to Allah. The balance between the two is where the line between work and play might not be clear; however, when Ali noticed that his football might come in between him and Allah, he knew he had to prioritize.

At teacher lunches, we often talk about our students, and a common refrain over the years has been a lack of patience and perseverance by young people. Our students don't want to mull over something or to dig deeper, the criticism goes. They want the answer now. Many of my colleagues blame video games and technology on this decreasing attention, and it may be true, but I often find myself resisting this blame game, and I wonder about how it is we are teaching and what learning looks like to our students. It does no good to cast blame on the kids in front of us if we aren't reflecting and changing what we're doing to ensure we meet their needs.
