That's unlikely, as Hue Jackson and John Dorsey have up until now been steadfast in the support of the starter, Taylor, who couldn't have been more efficient in his own Browns debut.
"I'm aware that it was the first game, and in that respect, it's not so bad", said Mayfield, the Heisman Trophy victor from Oklahoma. He showed the right mix of decisiveness and deliberation with his delivery.
After completing his first National Football League touchdown pass and throwing a strike on the run, Mayfield came up big once again. Mayfield hit fourth-round pick Antonio Callaway over the middle for a 54-yard touchdown in the third quarter.
The Browns let Mayfield play into the fourth quarter after he entered in the second.

One major hurdle to the proposal is that North Korea has not even disclosed how many nuclear bombs it actually has. But Trump has already given Kim some concessions, including ending joint military drills with South Korea.
He had three catches for 87 yards, including a diving 24-yarder that the Browns successfully challenged after it was ruled incomplete on the field.
It marked the second touchdown of the game for Mayfield and pushed his line up to 212 passing yards and two passing touchdowns on 20 attempts. Even though Taylor has heard time and time again from Jackson that he's the one come Week 1 when it counts, there probably was a sense he had to be beyond stellar to keep from cracking open the window for Mayfield.
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.
Overall, it was a solid start to his professional career for Mayfield.
