"I personally feel like I haven't done enough at Ohio State, the things I wanted to accomplish here, to move on to the next level," the junior running back said Thursday.
Asked if that meant he was leaning toward staying at Ohio State for another season, Wells said: "I don't want to say I'm leaning toward staying or I'm leaning toward going. All I'm saying is I do want to be the best Buckeye to ever come through here."
The Buckeyes, No. 10 in the BCS standings, play No. 3 Texas on Monday.
Two weeks ago, Ohio State coach Jim Tressel suggested it should be an easy decision. He believes Wells will be a top draft choice and that it may be time for Wells to go. Wells said Thursday that it's not so simple.
Wells ran for 1,091 yards and eight touchdowns despite missing three games after injuring his foot in the season opener.
Wells said he feels as healthy as he has been since that first game, but still didn't call himself 100 percent for the Fiesta Bowl.
Thursday's chat with the media was the first time Wells has been available to comment on Tressel's remark on his NFL future.
"If it were me, it wouldn't be tough," Tressel said Dec. 17 of Wells' impending decision. "In my opinion, he ought to be one of the first five guys picked."
Wells said the comment surprised him, but that it won't affect his decision.
"I really haven't sat down and thought about it yet," Wells said. "I'm really just enjoying the moment right now, whether it's, you know, a last game or not. I'm just enjoying it and focused on Texas."
Wells said he still wants to discuss it with his family and the coaching staff.
Wells rushed for more than 2,700 yards the past two seasons. Ohio State made it to the last two BCS national championship games, but lost both times.
"I wanted to be the best to ever come through Ohio State," Wells said. "I definitely feel like I haven't accomplished that yet."
Buckeyes linebacker James Laurinaitis, who could have left school early and chose to stay at Ohio State for his senior season, said two weeks ago that Wells has a lot to think about, including his injury history and how well his body will hold up.
"Running backs careers are shorter than most because of the hits they take," Laurinaitis said.
"It's an individual's decision," Laurinaitis added. "You can't listen to your high school friends because they're going to be like, 'Oh, man, take the money.' You should listen to the people you're close to. Your parents won't lie to you, Coach Tressel won't lie to you, your position coach won't lie to you."
