This is the best explanation I've seen. From the PS :
"Funderburk arrived at Arkansas in January 2011, but missed multiple spring practices and was allowed to return home to Virginia during the summer because he was homesick, according to
ArkansasSports360.com. Funderburk came back and eventually redshirted the 2011 season. He was listed No. 3 on the depth chart this spring, and had one catch for seven yards in the Razorbacks' spring game."
So he graduated high school early. Had a hard time adjusting, went home in the summer. Came back to Arkansas in the fall, redshirted, competed in the spring and then decided to leave Arkansas for good.
Not sure I see any red flags with that.
