Reynolds was my sleeper this year, and I grabbed him in 2 leagues. To be honest, I wasn't expecting this much from him this early. I was hoping for decent production mid- to late-year. I won't complain about this one bit, though. I still think his BA will lead to inconsistency, so I would carry a suitable backup if you have Reynolds on your team.
