Really?
Who were the serviceable guards available for low investments in 2014? Or 2013? Or hell, besides Richie in 2015? Not to come at you, but this is the team that signed Chris Williams for $13M with $3.5M GTD, and we cut him in one year.
I find the "easy to find" line touted quite a bit, even when the Bills have spent 2 years trotting out garbage at G. Either it's not that easy to find a serviceable replacement, or the guys looking are totally incompetent.
