Americas player is someone who does tasks set by big brother but he doesn't just do them, the public vote for the housemate he does them on like "Vote for a houseguest that Eric has to give a Teddy Too" and they vote for someone, which was Jess since Jess was Erics (BB8's AP) love intrest, and they vote for which houseguest Eric evicts and which hg he trys to get nominated, I personally think Dick and Dani wouldn't have got to the final if it wasn't for Eric Well america.

Here's a better explanation

America's Choice
America's Choice allows the viewing public to select a HouseGuest to receive a special opportunity not available to other HouseGuests. Voting is done through the CBS website and text messaging. Though HouseGuests do not actively compete for the reward, it is essentially a reward based on viewers' opinions of the HouseGuests. America's Choice contests begin midway through each season and occur weekly. Previous contests have allowed HouseGuests to make a mobile phone call to family, have a walk-on role for a CBS soap opera, and conduct an internet chat with fans. In season six, the first America's Choice contest was to vote a previously evicted HouseGuest back into the house. America's Choice is not always a choice between contestants to earn a special opportunity. Sometimes viewers are asked what challenge the HouseGuests should play or what kind of appliance would be given to the HouseGuests. In season eight, America's Choice spun off into America's Player, where Eric was chosen to fulfill tasks voted on by the public for financial reward.
