Mackensie Alexander raised his arms and pointed his index and middle fingers at his helmet. The move confirmed a check with linebacker Eric Kendricks before he turned to relay the call to outside cornerback Xavier Rhodes. He stood precisely 5 yards away from the Jaguars line of scrimmage, giving Alexander enough space to survey the offense's formation and make an educated guess as to the route slot receiver Dede Westbrook might run on third-and-6.
Wouldn't you know Westbrook ran a 6-yard hook route, slipped and watched Alexander break on the ball with precision to nearly intercept Blake Bortles' pass.
