Jaxson Dart looks like Giants’ future QB — and Russell Wilson now has less margin for error

Jaxson Dart had opened eyes in his preseason debut in Buffalo and now hyperventilating Giants fans inside MetLife Stadium would be getting their first up close and personal look at The Man Who Would Be King one day, their precocious new king.

But no one should doubt that he is ascending to it.

The more you watch him play the position, with composure and complete command, the more he closes the gap on Russell Wilson, and the more tenuous Wilson’s hold on the job becomes.
