I get the impression Alfie will never win a cup. This playoffs it looked like he wanted his team to get the cup for him more than he wanted to get it for himself. He wasn't very good, and I was extremely excited when he came at the beginning of the year.
Lower back pain can do that to you. I know from 15+ years of experience.
About Mantha - I'm not saying I think he's fully ready. Certainly I wouldn't expect him to be a key player right away. I'm just looking at our window with Z and D and K, and...it's closing. The future's pretty much here anyway. Might as well open the door. (Within reason, of course.)
