I didn't see this one coming.
I don't know if this puts the Lakers back in contention, but the addition of Steve Nash certainly changes the dynamic and fills in the holes they have had for a long time. Namely, Nash is a player who can deliver the ball to Kobe in better spots to make his job easier, he should make Andrew Bynum a much better player, and most importantly, he's probably the best pure shooter in the game right now, even at his advanced age.
Go to Silver Screen and Roll to see how the Laker fans are celebrating the acquisition.
Go to Bright Side of the Sun to see how they're coping. This should give you an idea: "Steve Nash a Laker, and a Traitor."
Steve Nash, I've been a fan of yours since you came into the league. Forgive me, but I kind of have to hate you now.
