Oklahoma quarterback Kyler Murray made headlines with his decision to commit to being a quarterback in the NFL. It appears the New York Giants are among the teams that already have their doubts.

One of the biggest knocks on Murray's future as a quarterback is that he lacks the prototypical size. According to Ralph Vacchiano of SNY, this will be why the Giants will pass on him in the 2019 NFL Draft.

Why? Because size matters to the Giants. They are still early in their evaluation process and obviously haven't seen Murray at the Combine or his Pro Day yet, but in general, a team source said he's “probably a little too small” for them. They prefer to stick to the established measurables they have for a prototypical quarterback.

Size has always been considered one of the first things teams tend to focus on, especially when it comes to the quarterback position. There is no question that at 5-foot-10, Murray is sorely lacking in that department. Fortunately for him, it has not been much of a precursor for success in recent years.

His former teammate and Cleveland Browns quarterback Baker Mayfield was faced with the same criticisms during his tumultuous draft process last year. However, he was able to draw inspiration from short quarterbacks like Drew Brees and Russell Wilson as players that are exceptions to this unwritten rule.

Regardless, Murray's prospects bode well considering all the quarterback-hungry teams in this year's draft. It will be interesting to see which point in the first round he gets picked up.
