I like walker....with driver becoming a fantasy DUD lately.....I dont think I would use him unless I did not have a better, more viable option though. He is the best play of the WR core in Green Bay.....and to answer your question, I think he WILL find the enzone this sunday against the chargers!

WR T. Owens, T Glenn
