While its tempting to overreact to the lack of news re the Rams, you have to remember that the teams that tend to make big splashes in free agency also tend to be the ones that struggle to ever actually get any better come September. The Dolphins do this every year but they never seem to actually improve as a result of it.
The media are pointing to the Broncos as an example of a team built on free agency but for every 2015 Broncos there are lord knows how many examples where that doesn't work. More often than not, the only thing it achieves is mediocrity and regular coaching/front office changes.
Let's see what happens today (its already Wednesday in the old world) and if we lose all of our free agents then you have my permission to panic but, until then, we need to have faith in Snisher and Demoff.
