Yeah, numbers doesn't always mean depth. But the kind of depth you're referring to, 88, is probably more often called 'geez we're stacked, you guys.'
And there's a difference between being able to list a string of names, and having guys who are currently projected to contribute or who are regarded as having lots of potential. Sometimes those names are just guys who have spent years in the program but have struggled through injuries or lack of progression. It's definitely easier to be optimistic when we're talking about new entries. But numbers are better than not and promise is better than 'hope these players turn it around.'
