To me it is funny how people will project .250 20/20 for Patterson and say he is worthless, yet this is not much different at all from what can be expected of Cameron, who everyone tends to love.
In my humble opinion, Patterson is still a good 4th OF option in a deep league. Views on him at the Cafe are distorted by 1) people who once upon a time invested heavily in him due to high potential and got burned and 2) bitter Cubs fans. So if you have a reasonable expectation for Patterson and are not counting on him to carry your team, you may be pleasently surprised if you get him for cheap. Yes he is high risk, but I would gamble on him for a couple of bucks.
