WRs not making attempt to go after balls that are deflected or when qb is hit.

WR logic on under thrown/ tipped balls seems broken. The WRs don’t go back to the ball or make any real attempt to get  tipped passes or balls when the QB gets hit, but the whole defense flocks to the ball with no issue. Happens a few times  a game would be nice if the intended wr or the other WRs stop routes to attempt to get the ball.
