Just looked and Corbin was the only arb case for the Brewers. Here is how that compares to other teams.
10 teams filed 0 cases
11 teams filed 1 case
5 teams filed 2 cases
1 team filed 3 cases
2 teams filed 4 cases
1 team filed 6 cases
Hard to see how the Brewers were trying to make a statement with that spread. Looks like a simple matter of the Brewers thought they had more accurately assessed Burnes’ value and they arbiters agreed.
