Here are some thoughts in the aftermath of Colin Kaepernick's huge new contract extension with the 49ers:ESPN's Adam Schefter reported that Kaepernick specifically requested his deal allow the 49ers flexibility to negotiate extensions with other players. Schefter reported that Kaepernick's signing bonus was only $12 million, which is at least half of the usual signing bonuses that come with big quarterback deals. Kaepernick mentioned at his news conference Wednesday that the deal will be designed to allow the 49ers to keep signing key players.
