i'd be ok with this, depending on the price. Just sign Cobb if you want to pay a bunch of money to a guy who won't throw 200 IP. This is my initial reaction, Duffy is getting 4/60 so it's not a money saver, and certainly the cost for Duffy is greater than the comp pick forfeited for Cobb. Knowing that the front office knows that too, brainstorming some theories why it would still make sense. - This is part of the Cobb negotiation, either to pressure him to sign or as a contingency if some team shows up with 5/95 for him - Duffy is a year younger, and while his injury history isn't pristine, it's fair to say he's a slightly healthier arm than Cobb, especially when you consider that age. - Duffy might have more room for growth than Cobb, Duffy hasn't yet worked with Hickey and he has better fielding-independent numbers - Since Duffy is getting near market rates, maybe his trade cost isn't all that high. I'm still skeptical, but I can see a path to it making sense.
