I made this comparison a few days ago...
2012 : 2013 :: 2021 : 2022
It's not a perfect 1:1 analogy but bear with me...
The 2013 Runner-up team was made possible because Trey Burke, Tim Hardway Jr., Jordan Morgan, Jon Horford from the 2012 team provided the core.
The 2012 class elevated the ceiling of the 2013 team with Nik Stauskas and Glenn Robinson who were ready to contribute from day 1 and became starters. It took Mitch McGary nearly all of the regular season to find himself but he exploded once he had improved. Meanwhile, Spike would provide flashes as a back-up. And LeVert (who Beilein thought would initially redshirt) started showing out more and more in practice until LeVert actually got significant minutes during the NCAAT.
