The dude has scored a number of memorable goals against the Burgundy Boys over the years and according to Daniel Boniface at The Denver Post,it looks like the Guatemalan playmaker is on his way to Colorado.
Nothing has been confirmed yet, but it does look like Pappa will be coming to the Rapids and a player like Pappa is certainly an upgrade in the midfield for the Rapids and could be a true #10 that is needed in Commerce City.
There is no word as to what the Rapids will be giving up to Seattle Sounders for Pappa, but I have to imagine it will be some sort of draft picks or allocation money as the Rapids are pretty thin on total number of players.
