Lil Wayne -- Alleged Bus Shooter ... I'm As Likely to Kill as Drew Brees

The man accused of shooting up Lil Wayne's tour bus now says the notion he'd try to off Weezy is as absurd as Drew Brees trying to kill rival QB Matt Ryan.

Lawyers for Jimmy Winfrey -- who's currently behind bars, awaiting trial for the shooting in April -- claim their client did not have a motive to hurt Wayne. The lawyers acknowledge Winfrey was an associate of Young Thug, but they say Y.T. idolizes Wayne.

The lawyers acknowledge there's rivalry in the rap game, but that doesn't mean rappers automatically want to kill each other. Winfrey's lawyers say, "Clearly, the New Orleans Saints and Atlanta Falcons are rivals because they are fighting every year to win the same division: the NFC South. Yet, this does not provide a motive for Drew Brees to kill or maim Matt Ryan."
