Haden said he is trying to figure a way to be in both venues for what will be a night of excitement and joy in Cleveland.The Browns will either be 0-7 or 1-6.The team recognizes that the Cavs title brought an explosion of elation to a downtrodden city. But the Indians success seems to have brought frustration that can border on embarrassment for the Browns.Im so happy for the Cavs, so happy for the Indians, Haden said. At the same time were one of the professional sports teams in the same city where theyre doing a lot of successful things.That the Browns are winless went unsaid.It puushes us, man, Haden said of the Indians success.dddddddddddd. We want to be successful. We want the city to embrace the Browns. We know this is a football town, but we want to get some Ws so they can show the same love and support that theyve been showing for the other teams.The Cavs have made themselves more than visible while rooting for the Indians. Twice in the playoffs numerous players -- notably LeBron James, Kyrie Irving, J.R. Smith and Kevin Love -- led the cheers from a suite at Progressive Field. Browns coaches and players are in season and havent been as visible at Indians games, but they were very present for the Cavs title run.Haden said some of the Browns players are working on something right now as far as a suite for the World Series, but itll be a tough task given the way the Indians have captured the citys heart.Looking at it from afar, I want to be in that spot, too, Jackson said. The basketball teams done it. The baseball teams doing it, and has a great opportunity to get it done. Our football team -- were not there yet. But all those teams were built to where they are now today.Were in our stage, too. We got to get there. But thats the goal, is to win a championship. ' ' '
