Can't disagree enough with this. First of all, heaven forbid we ever have a team that was dominating as the 2014-15 team. What led to their demise in the tournament was not because of using the platoon, but frankly because they didn't use enough of it IMO. As the season wore on, the less Cal used platoons and the further he went away from platoons the worse the team played. By the time of the tournament, Cal may have started with platoons in the early part of the first half but he soon abandoned it for the remainder of the games. In other words he was hardly using it the last third to quarter of the season.
Secondly, what's lazy is taking a deep team and articially reducing your rotation down because you can't figure out how to best manage numerous players, like Cal regularly did. Or worse because the coach couldn't be bothered to continue to develop his bench during the season so rather than be ready to contribute if needed, they end up demoralized by the end of the year and ready to transfer, another Cal specialty.
Platooning itself is a tool which allows for achieving maximum energy on the court at all times, which puts tremendous pressure on the opposing team. It doesn't have to be rigidly followed, there's a lot of variations that can be utilized within the basic framework and it doesn't even need to be utlized the entire game. But it is an effective way to wear down other teams while avoiding foul trouble, if used properly and if you have the right depth and talent and mindset to platoon.
Most teams don't have the depth to platoon. This year's team has the depth but it's not clear if they have the balance in the right places. To me the big quesiton mark is point guard. 2015 had Andrew Harrison and Tyler Ulis. This year's squad has Jaland Lowe and then a number of question marks. But if they were able to platoon, they shouldn't hesitate to utlize it. It's a huge advantage if done properly.
Edit: As far as recruiting. The kind of player Kentucky should be recruiting iMO, and what I believe Pope looks for, is someone who is talented but willing to sacrifice for the good of the team. If UK loses a recruit because they'd rather play somewhere else for 28 minutes rather than play 20 minutes on a deep UK team challenging for the national championship, then to me that's probably a good thing they miss on those types of recruits anyway.
