I've always thought R9 has the potential to challenge Pele and Maradona as GOAT during his early years. However, for larger part of his career (post-injury), he wasn't even among the top 3 or 4 forwards in his era, let alone best player at his time, or even among top 10 GOAT. If people rate peak/skills/potential over consistency/longevity/achievements, they could as well have George Best, or even Duncan Edwards (those with insane level of individual talents but didn't happen to achieve much or last long in their career) etc among GOAT rather than Pele or someone like Di Stefano (those with insane record of having greatest impact on actually winning most matches/titles). For me, the term "greatest" should embodied individual achievements and overall impact to the game, rather than just peaks and glimpse of highest individual talents.
