Delete/Replace Superimposed Image with tracking motion in After Effects

Hi,
im from argentina so sorry if my english is not the best.

i need some help. I want to erase a soccer player from the field while playing the match. I used to track him and superpose some green solid rectangles to emulate the green of the field. I also used a color position to change the color of the solid while moving around the field. I used this also to take advantage of the low resolution of the video.

Now i want to do it with all of the players. Repeating the process is not enough because the green solid turns out to be very visible and not as if it was part of the field. Also, some lines start to appear (corner, latter, center of the field, short and long area) and i cant continue using the same method.

So i was just thinking if there is any tool that can take a sample of the part of the field while the player is not there and then use it to superpose it when the player appears on that place. Its more-or-less taking the same position of the field but some frames before and using it afterwards.

What do you think?? is this posible? Consider i have to do it for almost 20 players and 1 minute long ;)

Thanks !!!

Maybe Mokey?

I was thinking Mocha is the tool for this, or Mocha AE can do the same thing with a little Photoshop work but sounds like getting the pro version will make this job a lot easier
