I think team 7 sucks because NOT ONE of them has ever won a big fight 1v1!
Not Kakashi, not Naruto, not Sasuke and definitely not Sakura! The only one who came close was Sasuke, twice, vs Danzo and vs Deidara. Vs Deidara he made him commit suicide but used Manda to take the blast but if Suigetsu etc hadn't brought back Manda Sasuke would've been done for. And vs Danzo, indeed Danzo was done for,but if Tobito hadn't told him to get away from Danzo Sasuke would've been sealed away by the reverse tetragram seal..
My overall thoughts on the whole issue are shown below:-
