Kobe Bryant's steely determination never wavers. It's his 34-year-old body he sometimes wonders about. He skipped the pregame shootaround because his shoulders were tight, and he was feeling weary in overtime. But Bryant found enough energy to hit the tying 3-pointer with 5 seconds to play in regulation, then dunked for the go-ahead basket with 10 seconds left in the extra session, helping the Los Angeles Lakers beat the Toronto Raptors 118-116 on Friday night for their second straight come-from-behind win.
