Could this cause excessive output drops on a link?

I have a link between a router and 3650 switch. The router’s interface is connected using an RJ45 cable, has 2k output drops, full duplex and using FIFO queuing. The switches uplink is full duplex using an SFP module. The interface is using class-based queuing.

There is nothing going on at the site, no collisions, unknown protocol drops, and late collisions. Where would you start with this? Stupid observation, but does the difference in QoS mechanisms on the link matter?
