He's seeing more smiles and energy.
"I could tell out there at practice," he said. "I don't know how it was when I wasn't here, but since I'm back, we're up, just amped. We're hyped. You know I like to talk. I like to have fun. I'm smiling, making plays. When we do that, me and (safety) T.J. (Ward) just jump up in the air and hit each other. Honestly, since I haven't been here, just going through every week and taking a loss, I'm coming in here fresh and bringing a spark, like let's get this thing going.
"Let's get it back on the road."
Haden has always felt the support from his teammates, many of whom stayed in contact with him during his suspension.
As for Browns fans, Haden believes they still have his back. He knows many were disappointed by his actions, but Haden has received "zero negative feedback" in the days since being reinstated.
While he was away, Haden, who likes to be seen around the city during the offseason, worried if his suspension would damage his relationship with fans.
"I like to interact with people and I didn't want it to put a damper on everything I've done because it's not like I'm trying to put on an act," he said. "I really enjoy having fun with people, so me not being able to do that kind of hurt me a little bit. But they accepted me back. I see how they feel when I'm not out there playing, they expect me to be out there. But I was mad at myself, so I think that just me being back now everybody embraced it so it's basically over."
Haden's suspension gave him a new appreciation for what he has. He has vowed not to jeopardize his career again.
Once he's on the field, Haden won't take anything for granted and he hopes the Bengals test him early.
"I'm ready, " he said. "I don't feel rushed. I just feel like I just missed a couple games and I'm right back. It wasn't like it was a downfall. I wasn't just in the house eating chips and stuff. I was doing what I needed to do, so I feel I'm right back and ready to play."
NOTES: With WRs Mohamed Massaquoi (hamstring) and Jordan Norwood (foot) out, the Browns activated rookie Josh Cooper for Sunday's game. Cooper was a teammate of QB Brandon Weeden at Oklahoma State and hopes the former college buddies can connect in the pros. "It's unbelievable," Cooper said of the chance to play with Weeden. "It's something you don't really see happen too much with other players. It would be nice to get to do that." ... Norwood was placed on injured reserve but is eligible to return to the roster in six weeks. ... Shurmur said the Browns hope to re-sign QB Thad Lewis, who was waived on Thursday to make roster room for Haden.
