How effective are analytics at the MLB level?

I don't really know. But I know how large the analytics departments are of nine MLB teams who have reported the size of their analytics departments in terms of # of employees. 

So here's the list of teams, the number of their analytics employees, and their number of wins.

Team         # Analytics Emps.   #of wins
Brewers           46                103
Rays              39                 98
Braves            19                 94
Phillies          51                 88
Guardians         30                 85
WHite Sox         19                 84
Pirates           35                 82
Giants            21                 65
Rockies           11                 58
