Each year, we run a series of post called "90-in-90" here at Niners Nation. The idea is that we'll take a look at every single player on the roster, from the very bottom to the top and break them down a few different ways. This is to help give everyone a basic understanding of a roster. Of course, this roster will change, and some days we'll have more than one so it's not strictly one per day but you get the idea.
The San Francisco 49ers did not invest 2017 draft capital in the offensive line, but they invested plenty in 2016 capital.
