How do you handle debut seas...Interesting analysis! How do you handle debut seasons (and debut age)? While many young players progress as Sterling has, with a 'cameo' season followed by a starting role, transfers from foreign leagues may go from 0 to thousands of minutes, which would give us a dividing-by-0 percentage change. <br />As for debut age, while studies on baseball have explored the connection between age-at-debut and talent level, I'm not familiar with similar work for football -- if a player first plays in the PL at age 20, do they receive 0s for their age-17 through age-19 seasons for these analyses? This is just intuition, but the playing-time increases pre-peak seem smaller than I would have expected.rusty_spatulanoreply@blogger.com
