I wouldn't rule it out but theres got to be something creative with this 8 man pen to make them contend early in the year. Anderson Davies Chacin works enough. Not pretty but enough. Woodruff Suter piggy backed at 4 could be a pen rest/break day if all goes well. Basically you look to woodruff to go 5. Keep him in the 150ip range. If he's not getting to 5 you throw jeffress to get to thru 5. Suter comes in for the 6th. If losing or up 3 he rides the game through the end. If its close you use knebel or even hader in the 9th. The question then is who is at 5. Yo, guerra, miley, wilkerson all get a quick hook and you do a psuedo pen day. If they can get 4ip you should be ok. If you can skip it, skip it. Basically going 6 starters for 5 spots and a 7 man pen. Trade long man ip and 5th starter ip for a deep start from the 4th starter combo. Gets far easier when burnes nelson peralta bump out weak links mid year.
