Within the TSN/SOM context, the first thing you must do is equate a run value to each card. This can be done based on converting the probable outcomes on each card into their respective baseball events and converting those events into expected runs. Every card has an offensive runs value plus a defensive runs value. Their are lots of articles both in these forums and online discussing the merits of Linear runs created models.
Once you have all of your players quantified, you must determine the replacement level value. This is the run level that is effectively free (i.e. $500k price online). What you are paying for online is the incremental value of runs above what the $500k player produces.
So the formula looks something like Player A runs creates - Replacement runs created= Runs over replacement level. From their it's just a matter of assigning $ values to each run above replacement level.
Note that because of salary caps and baseball position limitations (only 9 players can play at one time) the process of assigning $ to values above replacement levels is not linear.
The above fairly accurately describes the TSN pricing process in a nutshell.
