I don't think it's crazy to say we aren't AS DEEP as the other top teams.
Even this podcast acknowledges it briefly:

Whether you think that will hurt us, is a different question; as they do go on to say the top 8 will get the overwhelming minutes, as Fly Illini alluded to.
But, injuries can definitely play a factor.
I personally think we'll be fine as long as Zens, Brown, or Lincoln is able to be the same level of 9th man we've had in previous years, excluding Petrovic. It's always been my stance.
