Congratulations Phil Rogers, you have made a system that, get this, can tell us if a team has let people go or gained people through free agency and trades. Yes, thats right, you made a system that tells us stuff we already know. For a system like this to be of use, it needs two important things: A need and a way of predicting things. The first one, a need, does not exist as you have used the ability to add and subtract (yes, I know, major milestones for you) to tell us that the Cubs have traded or let walk more players than they brought in. Bravo. The second part, a predictive power, does not exist, as it will tell us very little, if anything at all, about how a team could do this season. All this is predicting is that the teams that have added will eventually clear roster space and the teams that have subtracted will add players, probably prospects/backups in both cases. So, to sum up, Phil Rogers has created a system that does nothing and predicts nothing. I have also made a system, except its even less complicated. All you have to know is how to count to 10. Just say a number 1-10 and act like it means something. For example: Red Sox: 4. This means that the Red Sox scored a 4, which is mediocre. They need to make changes to get it higher, otherwise they will not make the playoffs. San Francisco: 9. They are a virtual lock to contend. Does this make sense? Hell no. Does it accomplish anything? Hell no. Is it a "system" like Phil Rogers? Sure.
