I say team asuma barely because of the following reasons:
1) Shino vs shikamaru would be a good fight because they are both the stronger kids in there groups it depends on how much planning time they get because the least they get the better for shino. I would say shikamaru wins just barely due to his intelligence.
2) Kiba vs chouji, chouji would probably win because it is a deathmatch and chouji goes serious only if it is a life or death situation as for kiba he never won a single match. I would like to see gatsuuga and choujis rolling. Jutsu collide.
3) Ino beats hinata the minute she gets her in a mind jutsu
4) Asuma wins against kurenai but it would be odd for them to fight to the death because one minute they are having a baby and the next they are fighting a deathmatch
