Two errors that we already know about.
1) The elite-to-bust percentages in the QBASE list in "Rookie Projections" are reversed. We'll make sure that's fixed in the second edition.
2) In the Statistical Appendix, the negative signs got left off the DVOA ratings in two tables: Top 10 WR Better Lined Up Wide and Top 10 WR Better Lined Up in Slot. Will also be fixed in the second edition.
