Total agree with you in: Athletics, Cycling Road (may be a miracle of Sepulveda), MTB, BMX, fencing, Hockey, Football, Golf, Gymnastics Artistic, Handball, Modern Pentathlon, rowing, rugby seven, Synch Swimming, Volleyball and Weightlifting
Basketball: after the friendlys matchs, for me they can be defeated or defeat any team except U.S.A, i dont expect a medal for them but it isnt impossible.
Boxing: the judges makes this sport very unpredictable, i have a little hope for Melian......its a shame what happen with Yamil Peralta, he can figth in quaterfinals with the big candidate of gold, with the rest i agree.
Canoeing: in this case i disagree: i expect a semifinal for Rossi and a final of the k4 men, im more pessimistic with Rezola, i dont see him in the final.
Equestrian Jumping:it should be for the sorpresive silver medal of the Panamericans but i have a big faith in them, we can expected a diploma of the team, i agree with you in the individual performance.
Judo: i agree with Pareto and i think Lucenti can be a surprise, at least he can win a diploma for me.
Sailing: i agree in all except about Alsogaray in men Laser: he can be in the medal race for me.
Shooting: i think the sam of Gil but i have a little hope of final for the rest, except for Fournel who doesnt have any chance.
Swimming: you have strong reasons to think that of Grabich but i stil thiking that he can make semifinas/finals but i dont think a medal, i agree with the rest.
Tennis: agree in singles but you dont mention doubles, i see better chances there.
Triathlon: Tellechea can be top 10 for me
Beach Volleyball and Wrestling:its not impossible a diploma here.
