As much as I loved what Lehner did last year (and hope that he continues his success), he is in no way, a sure thing.
I really shake my head sometimes, reading posts about what posters think transpired, because 'we' just see the tip of the iceberg. We have no idea. Maybe he started going off the rails? Again, I admire his work and success, but addiction is a multi-headed beast. I bet we all know people who are high-functioning addicts. I am going to trust LL. We pined for someone like him, and now that we have him, we expect miracles overnight?
Varly is neither a slam dunk, nor an upgrade... yet. Why stress ourselves about something that seems so unpredictable? He has a decent history, how about we give him a chance?
