but now we are talking a vet who will expect to start at 2d, not necessarily upgrading the D, maybe not upgrading the O significantly , and making it tougher to for Deminosa to crack the line up.
Woah, woah, woah.
You of all people should know that bolded part isn't even remotely true.
These stats are from your (and my) favorite website Fangraphs.
Offensive runs above average based on park adjusted wOBA (basically, how many runs his bat is better than the average player)
Since 2002 when Fangraphs started tracking these things.
O-Dog : -0.8, -7.5, 2.1, -5.1, 4.3, 10.9, 8.2, 9.0 = Total = 21.1
Kennedy : 10.0, 0.9, 2.9, 2.0, -9.0, -19.1, -5.9, 5.9 = Total = -12.2
Guzman : -22.5, -15.8, -16.5, -29.8, 7.1, 6.0, -12.9 = Total = -84.4
I'd say its pretty obvious Hudson would be a massive offensive upgrade over Guzman, and a solid upgrade over Kennedy.
