Bursting with potential, Sullivan still has so much to learn about what it takes to be a successful wide receiver at this level.
He certainly has all the tools.
"I am picking it up pretty good now I believe," Sullivan said. "Making that switch was really tough, but I am working hard everyday to get down my fundamentals most of all. I am learning what it takes."
The coaches describe Sullivan as one who has unlimited potential, and a guy who can play on Sundays if he can put it all together.
"Getting in and out of my routes has been the toughest adjustment for me," he said. "I am kinda a big guy, so route running is something I have to do very well, and it is the area I need to improve the most.
"I'm working hard on improving my foot work and just getting better every day."
Sullivan is a part of a group, the wide receivers, that have taken the message of the coaches very seriously. Coach Bell challenged them to work hard be the ones who make plays.
"We talk about that all the time," he said. "Coach Bell always says if the receivers don't go the offense doesn't go. We know the pressure is high, but we'll keep working.
For now, they are going to enjoy the off week before really hitting preparations for SMU hard.
"Our main focus is working on our fundamentals right now," Sullivan added. "We have to take this week and worry about ourselves before we start looking at SMU."
One game at a time, that is the key phrase for the Eagles with what lies ahead.
"Every game is do or die for us right now," he said. "We know that we have to win every conference game or we probably won't be able to achieve our goals. Every one is big, starting with SMU in two weeks."
With the Eagles getting the weekend off, Sullivan plans to make full use of his limited time by going to go home to watch his high school play.
While he is home, he'll go spend time with family before gearing up for the rest of the season.
