I guess I understand it, but can't help feel like this is a typical Patriots, "We can get by with depth, saving money always works out," move.
Brady is old, getting older. Need a stacked, physical defense with athletic rushers.
Why can't the Pats ever get and hold onto elite defensive ends? Instead we get a line made up of "bargain" tackles and a "versatile" linebacking corps that is very good at keeping the score reasonable, but not dominating the line of scrimmage against good opponents.
Maybe they'll go ahead and sign Chris Long.
