I guess you can say Deion got relatively few picks; however, his relatively few is way more than Nnamdi's extremely low total. There really is no comparison.
Deion averaged 3.79 interceptions per season. He played 14 seasons and sat out 3 seasons before coming back to play 2 years with the Ravens at age 37. He was also a part time player for a small amount of time during his prime years while he dabbled in baseball. He never had fewer than 2 interceptions in a single season and had an interception for every 3.55 games played and one for every 2.96 games started. And his relatively few interceptions is still enough to rank 24th in league history.
Nnamdi averaged 1.36 interceptions per season. He played 11 seasons. Eight of those picks came in one season. That really drags his average interceptions per season down if you take out that year, which is clearly the outlier. He had 5 seasons where he didn't record a single interception. He had 9 seasons where he had 1 or fewer INTs. He got an interception every 9.53 games and one every 8.27 starts. Nnamdi isn't ranked in the top 250 for career interceptions.
Make it relative to whatever you want, Deion got far more interceptions than Nnamdi. Whether it is totals or averages, Deion far outpaced Nnamdi.
