He is still capable of being a good 4th liner who is can be a great defensive specialist.
He is far better conditioning and health wise than last year, he said his eye is almost just as good as before, it's no issue and unlike last year where he didn't get any time to train, he has had a summer of training, and wont be a step behind everyone throughout the entire year like last season, give the guy some time he will show his defensive skills. He probably won't be the 10/11 Manny, but once he knocks off the rust and gets going I could easily seem him as a great defensive 4th line center.
The jury is still out on Manny. I am sure the nucks management are hoping for the same improvement you (and all of us) are. Physically, he is in a better place than the start of last year. Let's hope he can recover his mental game and confidence and soon. There's not much time for him to find his mojo this year.
