Players seem worse in mid-silver than high bronze. Am I crazy to think that?

I have climbed all the way through bronze now and am currently sitting at silver III. I have noticed that in my past 5-6 games one of the two junglers has always been complete trash (sometimes they are on my team, sometimes on the other so I am not complaining about AHHH my jungler is always trash). In those games they have warded less than 5 times each, one jungler putting only one ward down all game. ONE WARD! How is that possible? I remember thinking when I was climbing that the macro play and warding was much better than it was years ago in bronze. Checking the post game vision score people bought at least one control ward, some people even two! I was thinking that in silver most peope will be getting at least two a person. Not the case at all. In high Bronze I felt like my teammates were working with each other most of the time and chalked it up to players in general just improving over the years lifting bronze up in general compared to those years past. However, in mid-silver it suddenly seems like people are clueless. Are they still dumping the new players into the silver 2-3 rank? Honestly, the adcs and junglers I have been playing with or against have just felt a lot worse all of a sudden.

Am I crazy? Anyone else have this experience?
