# Álvaro Fernández Carreras: a case study in portable traits and falsifiable projections > For the full version with images, embedded tweets, and visual breakdowns, [visit BallerzBantz](https://www.ballerzbantz.com/p/alvaro-fernandez). This piece shows how a lightweight, falsifiable scouting framework flagged Álvaro Fernández Carreras early and held up through his 2025 jump to Real Madrid. The approach centers on portable traits, role elasticity, improvement edges. It travels across leagues and coaches and is designed to plug into any recruitment process. Key principles demonstrated: 1. **Portable traits**: Skills and attributes that transfer across environments — pace, delivery quality, defensive positioning instincts. 2. **Role elasticity**: A player's ability to adapt to different tactical demands without losing their core identity. 3. **Improvement edges**: Identifying specific areas where a player's growth trajectory suggests they'll level up — not just current output. 4. **Falsifiability**: Making projections that can be tested and proven wrong, creating accountability in the scouting process. *(Visit the full article for the complete case study with archived projections and validation.)* --- ## Related - [[Maxi Oyedele]] - [[BB-wiki-1/Sports/Mechanics/Precision Play Mechanics]] - [[BB-wiki-1/Sports/Frameworks/Epistemic Certainty]] - [[Sékou Koné]]
