He goes into 5 players who will likely be second tier FAs this off-season who could be acquired for a team friendly contract. Link
He gets into a lot of discussion on the individual player and I'd go to his story for the details but the names are listed below.
RB Ty Montgomery
WR Jermaine Kearse
OLB/Edge Shayne Ray
CB Ronald Darby
S Kenny Vaccaro
Assuming that all will be available for short term "Prove It" deals, I'd be most interested in Ty Montgomery and Shane Ray. Montgomery always just gashed the Bears when we played the Pack and he averages close to 5 YPC. At 26 he could be a pretty cheap addition. And Ray could be an improvement over Lynch if Pagano and his staff could get him back to his 2016 performance (8 sacks, 6 TFL, 21 QB hits).
