https://www.google.com/amp/s/amp.usatoday.com/amp/702298002 If Baker Mayfield is going to make any kind of a run at the starting quarterback job as a rookie, he'll have to show big improvements in training camp. That's the verdict Cleveland Browns offensive coordinator Todd Haley rendered Thursday as the team wrapped up its three-day minicamp. As it stands, Haley sees Mayfield, the No. 1 pick in April's NFL draft, needing to make up substantial ground in order to catch up to Tyrod Taylor. "Again, that's yet to be determined,'' Haley said. "He has a long way to go. I'd say it's clear that Tyrod is the leader of this team. That is a big component of that position, also. What I will say is probably in my career, this is one of the best if not the best quarterbacks rooms in general that I've had.'' Haley said Mayfield had made "very good" progress but that his adjustment period could be an extended one. "Any time that you're a young player coming into this league, especially a quarterback, it's going to take time,'' said Haley. "You have a lot of different things that you're dealing with at that position. For him, a guy that has been in the (shot)gun 99% of the time, in this division you have to be under center some. Whether it's running or play action, those are some of the things that he has really had to work hard at." Browns coach Hue Jackson has maintained since the team traded for Taylor that the eighth-year veteran would be the starter. Yet Jackson has also told Mayfield to "keep working" in the break before training camp. "I made a commitment to (Taylor) and he has held up his end of the bargain with not just the way he works but the way he plays and the way he leads," Jackson said Wednesday. "He has earned the right to be the starting quarterback here." Taming his impatience has been a tough task for Mayfield, but for now his focus is on his own development. "Human nature, especially for me, is I want to have it all figured out right now, but that's just not how it works," Mayfield said Wednesday, according to ESPN. "It's about realizing we are going to have to take baby steps right now to get to where I want to go. You don't build a great castle just all at once. You got to build it block by block. "For me, that's how I need to handle it."
