I absolutely love this trade for you!!!
Roy is great and should have a nice year with TO the ball hog gone!
Celek had a nice first week and although I don't see him being a "monster" or close to Gates it's not that much of a dropoff!
Plus if you can swing a better TE later it shouldn't cost you much and then you will be set as Roy for a WR3 is Dominant!!!
Good Job and Good Luck!
