re: 2 dynasty trade offers- 1pt PPR

I don't know much about dynasty or how things work out in your particular league, but I don't think I like either of those that much. In the first I think you are giving up most of the future potential with Karlos. Personally I think that Tannehill can be a good solid qb, but I have my doubts that he will ever be great. He lacks the ability to throw the ball downfield. This might change depending on how much a 1st round pick is worth in your league and what kind of player you can expect to be available. That's the real wildcard that I don't know the true value of.

The second trade seems like a bunch for antonio brown. Brown is great, but that's giving up too much, especially with an eye on future seasons.
