I don't really follow the men, but wonder how a team that's lost three games can be the greatest team he's ever seen. Did he just start watching today?
The best explanations are contained within several thoughtful answers. The most significant element of the "greatest team... ever seen" claim is its built-in combination of limitation & integrity.

The human brain doesn't really develop sufficient capacity to conceptualize, formulate, and express a claim like the one quoted above until, say, 12 years of age. That means he could only possess the rare combination of awareness, attention, perception, and articulation since, at best, 2008.
The possibility that full "best ever" consideration had formed within a year or two of the notion ever having been possible seems extremely unlikely.
At that point, it would take a certain type of precosciously nerdy young teenager to be working on, working out, or working though such processes. Such kids exist.
I wouldn't be approaching your question and writing this response if I didn't have some of this type of energy in me, but it's uncommon and weird for the most part.
I wouldn't go anywhere near such an analytical breakdown and sincere response if I didn't first commit to not dismissing or disrespectful your query. That too is a rarity.
I'm regarding this as an opportunity to distract myself from multiple other discussions here that I consider off-purpose and against my rooting interest during these predictably anxious days of uncertainty prior to each weekend and each game in a win-or-go home setup that plays out as, in essence, 3 consecutive weekend tournaments that end most teams' seasons. In other words, I'm choosing to reply rather than speculating on future rosters, recruiting, the Transfer Portal, team vulnerabilities, opposing team fanbases offenses & idiocies, etc., etc. It's as though I think my absurd discussion is more elevated, less harmful, purer in aspiration, 'better' than the other stuff, which can be petty, low-consciousness, karma-distupting, and such.
In candor, I know that I'm 100% as foolish, counterproductive, worthy of ridicule, or just plain bad/dumb/wrong as anyone else here. The enterprise is branded as "Madness," and my enthusiasm is labeled with a shorted word form of fanaticism. I'm wasting precious life energy.
