how should we price multi-position eligibility? #6

I'm now thinking the value of multipositionality may be so roster-dependent as to be incalculable. Suppose we say a roster slot equals $1. If you add that to the price of a multipositional player, you haven't saved any money. A straight slot bump won't work.

Why are such players valuable? A. They can increase team depth by freeing up a slot to buy an additional backup with above-replacement production, or providing a second-level of backup for replacement level backups. An owner could cover all six hitting positions (C, 1B, 2B, SS, 3B, OF) with as few as two players, assuming one of them is the ridiculous Brock Holt of 2016.

B. The opportunity to obtain greater value in the future by freeing up a slot to spend on a prospect or sleeper instead of a backup player. The future value could come in the form of a prospect's above-replacement production or trading him for above-replacement production and/or cash.

In the first case, if a multipositional player has significantly more value over replacement-level, they are probably going to be a starter. If they are purely a backup, then maybe their value should be given by adding ((total zscore at each position)*(avg. GP of starters at position/162)) across all eligible positions.

In the second case, I don't know how we'd price this. It's the ultimate YMMV.

@thecza I like how you're thinking about this as a function of games played. thinking that over!
