Nelson and Heaps combined to lead the offense to five touchdown drives during Tuesday's practice.
"They were great today," said quarterbacks coach Brandon Doman. "I couldn't be more pleased with where they are."
Nelson completed 4-of-6 passes for 63 yards and three touchdowns and rushed six times for 48 yards. Heaps was 10-of-11 for 86 yards, with two touchdowns and one interception.
"We could have had one more touchdown, but Jake had a mishap in the 'blue' zone and threw an interception (to cornerback Brian Logan)," Doman said. "But, gosh, it was a heck of a drive."
The coaching staff is carefully evaluating both quarterbacks, to see if one emerges as a clear-cut starter. Doman said there's no real separation between Nelson, who's a junior, and Heaps, who's a true freshman.
"They're both playing so darn good. They're both so different and they have such unique talents. They're so different, and yet they're exposing their strengths and really doing a good job of what they do well. And they're moving the team," Doman said.
