Couple of thoughts
-Cleveland wanted Bradford and if they were under the assumption that Chip wanted Mariotta, I can see them offering the 19th pick for Bradford.
-With Philly being the one giving up picks, dropping from their 4th round pick to Cleveland's 5th round and giving up a 2016 2nd rounder, this just about rules out going after Mariotta.
-Pat Shurmur, the current offensive coordinator of the eagles, was with the Rams during Bradford's rookie season, so there is more evidence that no Mariotta trade is in the works.
