If the Rams do trade up from the second pick in the draft to the first, it is to get Jadeveon Clowney. But would it be worth it?
You have Chris Long and Robert Quinn, one of the most feared edge rusher tandems in the NFL. Clowney would provide an threat to Seattle's Russell Wilson and the 49ers' Colin Kaepernick, but what is holding the Rams down is a stagnant offense, not an inability to pressure quarterbacks. With needs on the offensive line and at receiver, getting an opportunity to bolster their roster with offensive weapons would be more logical.
Gaining more selections in a deep draft could allow the Rams to circumvent the "draft chart" and pick up a couple more picks that could become impact players on their roster. With possible trade partners such as the Falcons, Lions, or any of the QB-desperate teams could provide leverage to help find the needed pieces. The Rams could even trade the No. 13 pick to someone who may be interested if one of the top three quarterbacks is available.
The Rams still will have draft options at both OL and WR if they trade down.
