I think I would. I am not a Dickey fan but I also don't think he is this bad. If I could get him cheap, I would and this is pretty cheap. Just so much upside here and in a 10 team league, you should be able to find SP off the WW if this blows up in your face.
I'm just worried that Teheran's spring will translate (even though his first start was trash). I'm also worried that he may develop into the next Pedro and be a good keeper option so late. Although I have a ton of other keeper options and it's only 2 keepers per year.
So, I guess the first question is, should I even view Teheran as a keeper with all my other talent? If yes, then is it worth the gamble? If he's not then Teheran holds the value of someone in a redfraft league (not nearly as much). In which case would you make the Teheran/Dickey swap?
