Trust seems like the biggest obstacle with Poole and Livers as Dylan said. But I think when evaluating the quality of team depth, there’s a difference between JB not trusting his freshmen 9th and 10th guys vs. the 9th or 10th guy being an Andrew Dakich, Blake McLimans, Matt Vogrich type as we have seen previously.
Here’s another way to put it from my perspective, in past years I think if the 5 starters scrimmaged the 5 backups in a 40-minute setting, the starters would win by 40+ every time. This year, if Brooks, MAAR, Matthews, Duncan, Wagner played Simpson, Poole, Watson, Livers, Teske, the first group would obviously win but I think it’s far more competitive than any previous JB season. (Other than maybe Spike, Vogrich, Levert, Horford, Morgan during the runner-up year but that team’s starters were so good it’s still an enormous blowout)
