CLEVELAND, Ohio -- With the Hard Knocks cameras capturing his every move, No. 1 pick Baker Mayfield had a rocky first organized team activities practice open to the media.

Mayfield, third on the depth chart behind Tyrod Taylor and Drew Stanton, threw three interceptions in the 105-minute practice, and had another two passes that were almost picked off. But two of the three picks went off receivers' hands and weren't really Mayfield's fault.

In 11-on-11 goal line drills, a pass at the left side of the end zone went off Seth DeValve's hands and into those of fourth-year defensive back Derron Smith for the first of Smith's two picks. In a subsequent team drill from the offense's 30, safety Jabrill Peppers dropped a Mayfield pass intended for tight end David Njoku over the middle, near midfield.

"Kind of tried to get a little highlight play instead of going up there and getting it, but still should have caught it,'' said Peppers. "It is what it is."

In a 7-on-7 drill, Mayfield was picked off by linebacker James Burgess on a 20-yard pass over the middle, and two reps later, his 30-yarder to Evan Berry went off the receiver's hands and was almost swiped.

Finally, on the last snap of the day, Mayfield's pass was tipped by cornerback T.J. Carrie and picked off by Smith, who was all-Berea, as former Browns coach Butch Davis used to say.

But it appears the Browns are working with Mayfield on specific things, including the dangerous territory over the middle. What's more, he's learning to operate from under center, which he did just seven of 1,047 snaps last year at Oklahoma.

But Mayfield also flashed some of the ability that made him the No. 1 draft pick.

He threw a touchdown pass in the back left corner to rookie tight end Julian Allen in team goal-line drills, and completed a 15-yard slant to fellow rookie Damion Ratley over the middle in a team period.

In 7-on-7s, he hit Njoku in stride about 30 yards down the right side, and the second-year tight end ran it in for a touchdown. In a later team drill, Mayfield, operating under center, pump-faked and delivered a perfect intermediate ball to tight end Devon Cajuste.

All in all, it was the kind of up-and-down day one would expect from a rookie, but he's also working primarily with the second- and third-team offense.

Jackson stuck to his plan to make Mayfield work his way up from No. 3 on the depth chart. He also re-iterated that the Hard Knocks crew, which began filming Wednesday, will not alter his plans for the quarterback rotation, and that the show won't stir up a controversy.

"Tyrod's our starting quarterback. Baker's our No. 1 pick," he said. "He's our quarterback of the future. I've said that since this happened. I don't think that will change. I want those guys to be exposed for what they do, because I think our fans want to know them and what makes them tick. But at the same time, I don't think it should put any more pressure on what we need to do as a football team about who's playing quarterback for us.''

While Mayfield had some growing pains, Taylor looked comfortable and in control. He ran in for a TD on the goal line, and completed several other nice passes, including a deep ball to Rashard Higgins in an 11-on-11 period.
