RMD version: https://rpubs.com/chadgordon09/step10 1. The next logical step is to take the same methodology we used for attacking and dive deeper into the rest of the skills. If eV+ can help us better evaluate attacking, then perhaps it can be useful in other portions of the game. 2. Again, I'll attempt not to burry the [...]

for RMD version: https://rpubs.com/chadgordon09/step9 1. Expected Value Added (eV+) is simply: Results minus Expectations. 2. Building on the logic from the last two posts (Step 7 - Expected Value in Attacking, Step 8 - Expected Value of Input Situations) we merely combine the two to determine the value of each touch. Output eV comes from [...]

Block touches; if you're wondering where they are - [...]

I'd also argue it's the most interesting, least understood, and most dynamic of our game - making it the best place to pick some low-hanging fruit. 2. We need to understand the reality of attacking. As you [...]

If you haven't noticed, big Moneyball guy over here. But that one line really cuts to the core of the issue. If he's a good hitter, why doesn't he hit good? 1. In our case, the problem is not that there are rich teams and there are poor teams...but that we are not evaluating the [...]
