It's hard to predict trade-up scenarios. I only see them as being valuable if a player you were really high on starts sliding out of the range you had him projected at. With the late surge up the consensus rankings of players like Quinn, Sanderson, Jarvis, etc; I could see one of the guys at the bottom end of my "top-9 lock" tier (Lundell, Holtz) unexpectedly slide to 12+. For players sliding in the second round and beyond... they've really got to slide for me to see the value in trading up to nab them. Luke Tuch is not a player I see sliding, or the value in jumping to the 34-42 range I currently have him in.
