A classic case of the skin deep stat viewer. You do realize Amos played in 13 games this season right? Apparently not because you're trying to make it sound like he had less production while comparing him to others. Ironically you also name drop Morgan Burnett while leaving out he played 12 games this season and Tavon Wilson which played 10 games.
Furthermore you go on to talk about Andrew Sendejo who also played 13 games while apparently not taking into account he is a 6 year starter at safety and 8th year NFL pro who just so happens to be on one of the best defenses in the NFL. Taking those things into account, I am not particularly impressed by his 2 interceptions on the season nor the 6 interceptions he has for his career. He has 75 tackles though, cool story bro. Safeties are judged and graded by the job they do on the tackles they are asked and tasked to make not the number of tackles they rack up. If you want to judge Amos based on a lack of interceptions then so be it. I can't tell you what to think.
I'll just leave this here and drop the mic:

Adrian Amos
PFF Grade: 92.0 (Elite)
Elite Stat: Among safeties with 30-plus targets in 2017, Amos tied for fourth in yards allowed per snap in coverage (0.47).
Chicago’s Adrian Amos is seen by many as just another guy, but his ability to simply make the plays you expect a safety to make is not to be underestimated. Safeties by their nature are almost contingency players, coming downhill to add to run fits and adding coverage help on the back end to shore up the cornerbacks.
Amos notched 26 defensive stops, just two fewer than (Harrison) Smith managed on almost 300 fewer snaps. He may not make as many splash plays as other players at the position, but he makes all the expected plays without making mistakes.
