Rangers seeking rotation help

What are we going to do Nolan?

Believe it or not: The Texas Rangers are among the league leaders with a 4.17 E.R.A yet they are still seeking a starter via trade.

Current Rotation:
Kevin Millwood 9-7, 3.39 E.R.A., 1.28 WHIP

Scott Feldman 9-3, 3.59 E.R.A., 1.14 WHIP

Vincente Padilla 7-5, 4.67 E.R.A., 1.52 WHIP

Tommy Hunter 3-1, 2.00 E.R.A., 1.17 WHIP

Derek Holland 3-6, 6.13 E.R.A., 1.62 WHIP

Now imagine for a second replacing Holland with one of these guys:

Zach Duke 9-9, 3.42 E.R.A., 1.23 WHIP

Jarrod Washburn 8-6, 2.71 E.R.A., 1.06 WHIP

Cliff Lee 7-9, 3.14 E.R.A., 1.30 WHIP

Lee could be headed to Boston according to T.R. Sullivan, but Texas still remains rumored to get Duke and the Rangers have a scout watching Washburn pitch tonight in Seattle.

Of the three, who do you want? I still would choose Duke because he would be the cheapest and we could hang onto him the longest.
