I share the same opinion as most. Its 2B or bust for Biggio. Having him learn different positions has stunt his development.
As pointed out, in his first 159 MLB games (all of 2019 and 2020), he had a 5bWAR or 3.7 fWAR and a 116 OPS+ or a 117 wRC+.
If he does that again in 2022 at 600k you are laughing. If he regresses to a 2-2.5 WAR player you are still happy with that because the average fWAR for an MLB 2B starter was;
2021: 2.9
2020: 2.7 (prorated)
2019: 2.2
2018: 2.2
2017: 2.2
Average is 2. 4 fWAR. So if Cavan regresses to a 2.5 fWAR player you have an average 2B. Not to mention other potential 2B options like Espinal, Smith, Groshans, Orelvis and even Moreno who camp as a SS.
