Our captains were set up to be NMart, Day, Schmidt long ago. Farley was the inside favorite for lots of reasons, plus he could be labeled "captain for the special teams" if anyone wanted to rationalize it. THAT's where most of us thought that it would go, if you revisit the thread. The only surprise was making Jaylon a captain, despite that job not meeting his personality. My guess is that Coach just wanted to honor him for a fantastic career, since he'll likely not be back [sadly] next year.
As to Ronnie, Nick has made it almost violently clear that the "ordering" of the OLine is HIS job, and everyone else is to shut up and just blast people. Ronnie seems to do his big brother thing for Quenton and Bars, but leading the OLine is Nick's job. Frankly not having to act like a formal captain is just one less responsibility to be relieved of so you can just play ball [which is why Kelly hasn't considered making Jaylon captain any earlier. ... and one more subtle way that Joe helps us.]
I DO wish that folks would stop creating negative interpretations out of the flimsiest of assumptions, though. Seems almost like a board disease.
