New Cleveland Browns coach Hue Jackson knows what he wants in a player and what the team saw from Johnny Manziel over the last two years is not it.

Manziel is widely expected to be released next month after a string of off-the-field incidents and other distracting antics.

"That behaviour will not be tolerated," Jackson said on Wednesday inside Lucas Oil Stadium at the NFL Scouting Combine. "I want to leave it at that.

"Our organization is going to take a stand. We’re going to move on from those types of situations."

Jackson said he would "stand by" the statement released by the team on February 2 that condemned Manziel's antics and said his status on the roster would addressed soon.

Manziel threw for 1,675 yards with seven touchdowns and seven interceptions in 14 games over two disappointing seasons after the Browns traded up to select him with the 22nd overall pick in the 2014 NFL Draft.

Manziel's dedication to football was questioned during a tumultuous rookie season. The Browns hold the number two overall pick in this year's draft, and they are again in the market for a quarterback.

"What we're looking for in a player is, obviously a high-character guy," Jackson said. "I want guys that have high football character. That being said, we're also looking for people who are tough; guys that have passion for the game of football.

"It's about team. What I want our players to buy into is we're going to be a football team that will be accountable to each other. We all know accountability goes both ways. We'll be a group that's hard-working. We'll have some grit. We'll be physically and mentally tough and be resilient."

Jackson wants to change the mindset in Cleveland of what the Browns have been.

"It has to start some place," Jackson said after praising the support he's received from team executives.

Jackson said the Browns will use free agency to supplement their roster, but building a sustainable winner has to be accomplished through the draft.

"I promise you this, we're going to put a football team out there that will compete and play hard," Jackson said. "I think we're excited about where this can go."
