From the evidence I've seen, they do not. They built a full size basketball court, yet their chapel is basically a side closet. 
Well, let's be fair. Benedictine Monastic practice tends to have monks spending most of their non-labor time in their cells (aka the bedrooms), and they do not have the Blessed Sacrament there. So advantage they might have from a "chapel" is to get together to say the Office in common during the designated hours. Sure, if they had the Blessed Sacrament, certainly they would want to do better for a chapel, as presumably it would also need a sanctuary, an altar, etc. But without the Blessed Sacrament, it's just a place to sit together to say the office.
Let's also consider the source of this diagram in terms of whether there's exaggeration here, as based on that it barely looks like one person could fit in there at at time.
Guy who put this out there has a massive ax to grind against the Brothers, so it's to be taken with a grain of salt.
And I find nothing wrong with a basketball court.
