Mayfield said he didn't experience any jitters in his preseason debut, but did acknowledge that he was glad to get the first game under his belt.
Second-year tight end David Njoku caught two first-quarter touchdown passes - one from each quarterback. Last season coach Hue Jackson led the Browns to a ideal 4-0 record in the preseason.
Mayfield returned in the third quarter to spin additional magic, rolling to his right on a third-and-7 from his own 22 to find rookie Antonio Callaway along the sideline for 24 yards. He then almost found controversial rookie Antonio Callaway, in the lineup only days after receiving a marijuana citation that he didn't immediately inform the Browns of, on a deep shot that Callaway couldn't locate.
50 - The Browns, who expect to run the ball quite a bit in Todd Haley's offense, only had 50 yards rushing on 33 carries.
Overall, it was a solid start to his professional career for Mayfield.
Mayfield's final numbers (11-of-20 passing, 212 yards, 10.6 yards per attempt, two TDs, 125.4 rating, one sack) were nothing resembling those of a raw rookie trying to transition from college spread to pro-style, albeit against Giants backups playing vanilla schemes.
