The obvious knock on Murray is his size. It is difficult to imagine him being able to withstand multiple big hits by NFL caliber defenders. Murray undeniably benefited from playing against mediocre Big 12 defenses. Height is also an issue when Murray is faced against defensive lineman who have a tendency to knock passes down. There is some concern about Murray having the option to return to baseball. If he fails at first in the NFL, it isn’t unrealistic to think he could consider a return to the diamond.
