Why only six, I say? I'll base my decision based off the PlanetKubb annals, and what I have seen in tournament play. Obviously the teams may change based on chemistry, as you could have the best stats on record, but not mesh well with the team. So here it goes:
My 8-meter specialists
Aaron Ellringer currently has the highest percent of players that don't throw first at 63.9 percent. And these are not all stats from a 2 person team. Aaron has many 3-person games logged that some other "Franchise Players". Either way, he is accurate.
Grant Scott is at 60% - and he generally goes last. Grant has stats from Nationals going 2nd, and stats from Loppet going 3rd. Maybe a few 2-person Los Padres in there as well. Grant is a competitor, and will do everything he can to help his team win.
Goplin is at 60% on baton hits, having 3 2-person team games recorded, 3 3-person team games recorded, and 2 SIX person team games recorded. He can hit 8 meter, and he is no slacker in the field, especially clutch. I do not believe I have seen Goplin miss 1 field kubb with the last baton.
Dave Ellringer edges Mark Blazel out in my mind at blasting.....barely. Dave is at 75.9 percent and generally goes first. Mark is at 74.4%. Dave goes first, and Mark cleans the rest up.
Scott Forster - Whether he knows it or not, he is my nemesis. In a good way. He is the guy I want to play at Nationals. Precision, lofty, flat drills. He can make groups that can get blasted. Not much cut left to right last year, but rest assured, he is working on it this Spring. Scott's the driller for Team USA, and don't forget about his 8 meter shot.
King Toss/Team Coordinator:
Chris Hodges will perfect his King Toss throw in a few months, and when he does, not only will you do a double-take, you will also lose. Chris also has the logic, strategy, and the drive to make the best decisions for the team. He will help with spotting the driller, entry point for blasts, opponent rules violations, and determining throwing order.
Eric Anderson has the ability to say the right things at the right times to his team. He knows the game, he knows Swedish, he has coaching experience, and he has experience playing at Worlds. He has everything Team USA would need to make a run for the title in Gotland
P.S. - If I didn't pick you, you should be horribly offended or something.
