Interceptions were one stat in which Rattler was OK -- 5 INTs in 228 attempts. That puts Rattler, in interception percentage, about the same as Jared Goff and Jordan Love, and considerably ahead of Baker Mayfield and Brock Purdy.
That said, Rattler has to improve on pretty much all the other QB stats. He also has to work on his fumbling (five lost in six starts). He's still a young player, and it's way too early to throw in the towel on his career.
