I think they use two 5th to get into the 4th. I hope they don't spend a future 2nd to get into the 3rd. I think 2nd round picks are too valuable to give up and actually wish they would trade 3rd found picks for future 2nd round picks. (I know we don't have a 3rd this year, but I hope they do this some in the future.).
My wish is that they trade back some in the second in hopes of getting a 3rd this year. There seems to be lots of talent available in the 2nd so a trade back would seem like a good idea and some of that talent might slip to the 3rd. But, they will probably trade up for a guy they really like in the upper 2nd.
