Alexander's instincts and route recognition are next level quality. He can be seen in several clips releasing his man and picking up another one up based on what he sees developing.
He plays the ball extremely well and does a great job positioning himself between the ball and his receiver to limit the offenses options and opportunities.
In addition to being a good cover guy, Alexander is very decisive when coming up in run support. A great open field tackler, Alexander is capable of shutting down his side of the field in more ways than one.
