Jaromir Jagr could not put a time frame on his NHL negotiations but had nothing but great things to say Tuesday about the Pittsburgh Penguins and Detroit Red Wings, the two front-runners to land the 39-year-old winger."I don't know," Jagr told ESPN.com when asked how much longer his decision would take."Sometimes it takes a few hours, sometimes it takes a week. I'm not sure how long it's going to take," added the five-time NHL scoring champion.Jagr's agent Petr Svoboda told ESPN.com earlier Tuesday that the Penguins and Red Wings were front-runners for Jagr's services as well as a third, unidentified team.
