I would describe Oscar Vera as a very good prospect in TEW terms. The big problem with newgens, is that most don't have any where near as balanced a stat spread as Vera does. Too many people have good SQ but terrible mic skills and in ring stats. Others have a terrible look and single digit Psych, but a 45 in technical. Most don't spawn with any stats above the low 40's. Even fewer have multiple stats above that range, and almost all newgens are terribly deficient in at least one key Area.
This problem is compounded by the slow pace at which workers develop their skills. Even prodigies, wrestling many times a month, will likely only see 4 or 5 point attribute increases yearly. Fundamental skills like Basics, and Safety can and do go up very quickly, but not other stats.
A newgen whose best in ring stat is at or around 30 (which is common), will need around a decade just to become half decent in ring. Since it is often hard for young, untalented workers with low pop to get booked, many prospects don't get enough matches to even attain that modest level of stat growth. This tends to kill long term saves as eventually, there just aren't enough good workers to go around.
