The Tennessee Titans organization can't rely on Marcus Mariota. For all of the quarterback's natural ability and athleticism, he hasn't stayed healthy—which severely hampers his and the Titans' long-term potential.
Mariota left Saturday's 25-16 victory over the Washington Redskins during the second quarter after being slung to the ground by defensive lineman Jonathan Allen. The team designated the quarterback's injury as a stinger, according to Jim Wyatt of the Titans official site.
Another injury. Another disappointment. So much hope rested on Mariota's hampered shoulder, yet the Titans don't have any indication the 2015 second overall pick can withstand the physical demands necessary from the game's most important position.
