Optimal Choices – Serve pt.2

Had a thought while glancing over what I posted the other day. It makes sense to look at both the start and end zones for the serve, but also who you're serving. You can serve into zone 5 but if the middle back passer takes it, that's a different efficiency (and a different angle) than [...]

Service Error and Eff Change

Here is what team service error% looks like graphed against the average Eff Change per serve in each match. Again we see an inverse relationship between the two [...]

Service Error and FBSO

FBSO is of course indicative of your opponent's ability to win the point on the opening possession - but what many overlook is losing on the opening possession. What you see graphed along the y-axis is "FBSO efficiency", meaning we subtract lost points on the 1st [...]

Serve tough until enough parents in the audience complain?? (Side note, listen to Becks talk serving if you never have) The first step coaches usually take [...]
