While I certainly won't be missing Millar on the roster, this isn't true. Look at the stats.
1999-2005
OPS+
Millar: 107, 119, 141, 131, 110, 117, 100
Erstad: 74, 137, 78, 88, 75, 95, 89
EqA
Millar: .277, .289, .311, .300, .274, .284, .262
Erstad: .225, .306, .243, .247, .233, .263, .247
League average is 100 for OPS+ and .260 for EqA. Millar has had one league avg. season (2005) and six above avg. Erstad has had one above avg., one at avg., and 5 below avg.
