​Younghoe Koo only managed to play four NFL games before ​being cut by the Chargers in 2017. The 24-year-old kicker struggled to convert on long field goal attempts, going 1-of-4 on kicks from 40-49 yards out, resulting in the ​Chargers moving on. 

The South Korean kicker has since joined the AAF, as he looks to work his way back into the NFL and he's doing a great job early on for the Atlanta Legends. 

Koo has gone a perfect 10-for-10 on field goal attempts in thee AAF thus far, an encouraging sign for the former Georgia Southern kicker. 

The Chargers signed Koo as an undrafted free agent back in 2017 after he had kicked for two seasons at Georgia Southern. While in college, Koo converted on 96.9 percent of his extra-point attempts and knocked in 26-of-29 field goal attempts. 

Koo is certainly going to have teams keeping tabs on him, as he works to improve in the AAF. His accuracy has been excellent early on for the Legends, so hopefully he can maintain his solid form and turn it into another NFL audition.
