he liked Micah Hyde, I'll give you some funny misses just using a bills search:
As for the Rams, this was an outstanding move for them. They lacked a No. 1 wideout - Robert Woods and Tavon Austin were battling for that distinction - but now Jared Goof has a lethal target at his disposal. Sure, Watkins has injury concerns, but he's absolutely worth it based on what the Rams gave up for him. Going from a second to a sixth and trading Gaines is not a big deal if it means adding a Pro Bowl talent. The Rams won this trade by a long shot.
Grade for Rams - A+
Grade for Bills - D
Bills sign WR Anquan Boldin (1 year, $2.75 million): A Grade
This signing almost makes too much sense. The Bills have needed a No. 2 wide receiver for quite a while, and even though rookie Zay Jones could end up being that player, he's an unknown commodity right now.
Bills sign ILB Gerald Hodges (1 year): A Grade He liked Micah Hyde
Bills sign S/KR Micah Hyde (5 years, $30M; $14M guaranteed): B+ Grade
Hyde can do plenty of things. He can play nickel and safety, and he can return punts very effectively. Hyde can also simply match up against opposing tight end threats and cover them well.
Bills sign K Steven Hauschka (4 years, $12.4 million): D Grade
**** that Hauschka was amazing, I hated Carpenter.
Bills sign FB Mike Tolbert (1 year, $1 million): B Grade
I think Poyer was too lowkey, but he usually gets literally every FA move.
I don't really know where else to look for an analysis on every FA decision with a write up. I doubt anybody else spends as much time compiling that for every team.
