Risk is the odds of keeping less than 80% of platform-year portable production over the two seasons after signing. Bands anchor at measured 2019-2023 rung-by-spike rates (incumbent 23.5%, external 43.5%; with a career-year spike 36.7% and 56.3%) and the age-cliff flag escalates one band. Expected retention comes from a frozen regression on the same frame; portability flags are advisory until a larger sample prices them. Odds, not verdicts: the incumbent ladder is the best public sensor for what stats cannot see, and it is probabilistic. Guarantee share is the expiring deal structure; dead-weight risk concentrates where heavy guarantees meet career-year spikes.
Team fits are provisional and only appear for players in the top positional market tier. They use roster need, cap commitment, and recent team results. The model excludes the incumbent because re-signing is a different scenario.
