dont know exact worth in trade . but i will say glenny is an excellent addition to a 4th line / pk unit . smart , rugged , determined , hustles . you will hear all wing fans talk about his mentoring of young guys because hes an obvious competitive force thats making smart plays all 200' to prevent opponant chances and get his team possesion . he just doesnt have a shot to score more or the hands to play make . if yzerman trades him there will be many teams wanting him , and i wouldnt doubt hes put in a package with somebody like ryan or bernier . or in a deal where 50% is retained and detroit takes back an expiring bad contract so detroit aquires a better future than just glenny being traded on own
