AgingCurve
A fantasy baseball advisor that flags buy-low players coming off injury or cold streaks by adjusting Statcast quality-of-contact for age and role, so managers stop panicking about the wrong veterans.
Season-long fantasy baseball managers in competitive leagues
- Buy/sell rating that blends recent Statcast barrel rate, chase rate, and injury-return ramp against a position-specific aging curve
- Injury-return tracker with projected weekly ramp so users know when a returning star will be back to peak output
- 'Don't give up' report that surfaces elite players in cold streaks the league is widely down on, with a confidence banded trade-target output
- Waiver-wire digest tuned to category needs (power vs. speed vs. ratios) so pickups match the user's roster gap
