There was definitely some questionable calls in favor of the Lakers, but down the stretch the warriors still had two opportunities to win the game and they couldn't do it. I see your argument though, in your opinion the lakers had no business being in the game.
One thing I will say though is the lakers have 3 hall of fame players on their squad that alone is going to get them some favoritism by the refs. Also helps the lakers that those 3 players live in the paint and draw a lot of fouls. Curry and Thompson will soon be getting that type of treatment if they can consistently play at an all star level and from what i have seen that won't be a problem. You have to earn that type of favoritism from the refs, harden has been added to the list of portected all stars and curry might be just as good as him or better.
Also props to Jim Barnett he has to be the most unbiased announcer in all of sports. I swear while watching the game as a lakers fan I never once felt like he was drooling over the warriors while shitting on the lakers. I respect his opinion and even he called out the refs, something I rarely see him do.
