Which FA signing will be the biggest difference maker?

[Mike M (the other one)]

While I like what XSF brings.
I have to go with Reader being the most impactful player. Him in between Los and Geno with Hubbard.... that's sick. 4 guys that OL have to pay attention to all day long or else someone will be in the backfield
It's not like double teaming 1 or 2... but 3.
