Colin Kaepernick's Attorney Calls BS on Roger Goodell, You Think Mark Sanchez Is Better?!

Colin Kaepernick's attorney just went off on NFL Commish Roger Goodell -- claiming his explanation that teams just don't think Colin can help them win is the biggest crock he's ever heard.

And, Kap's lawyer is using Mark Sanchez to make his point.

Mark Geragos appeared on "Today" Thursday and was asked about the comments Goodell made at his State of the NFL Address this week ... when Goodell said Kap's unemployment status is based on football, not politics.

"Anybody who believes that will believe that Mark Sanchez was a better choice," Geragos said ... noting several other QBs who are "well past their prime" were also signed this season.

Geragos also asked why NFL teams did NOT give Kap a workout in 2018 -- "Why didn't anybody ever bring him in and see where his skills were at? I think the whole thing is basically a ruse."

Geragos believes Goodell's statement will help Kap's collusion case against the NFL -- saying, "The collusion actually was the NFL kowtowing to [President Trump]."

He also says ... "There isn't anybody who's got a couple of neurons firing that wouldn't say this is collusive activity."

For the record, Mark Sanchez was signed by the Washington Redskisn at the end of the NFL season after starting QB Alex Smith went down with an injury.
