Required salary for one. 

Are all the companies selling "fitba software" selling the same or a similar product and will teams selected this way become generic & predictable? If so, bucking the trend where you sorta know other teams plans could work, or maybe not! 

Using one players is rather silly and futile.  It's 2026 and maybe it's time you moved with the times.  Metrics are an additional tool in the process, not the only factor.
