Yeah But ...
Say the Rams trade down 10-12 spots, into the mid-20s for a 2nd round pick.
That trade partner's 2nd rounder will Also be towards the end of Round Two (just like their 1st rounder was); and would probably be in the mid-to-late 50s. Even if Boston falls, do you see him falling that far?
Now there are probably one or two exceptions. One I can think of is Cleveland which has Jacksonville's #1 which is 24th overall, and their own #2 which is 39th overall. If Tyson and Lemon (my two favorites) were both off-the-board, I could be down with that type of trade (#13 for #24 and #39) but not for Simpson. Cleveland has lots of needs and there would have to be someone they love at #13 to consider such a trade.
