I believe it. Their original pick was #12 so they most likely were thinking they could miss out on a QB entirely. Lawrence & Wilson were 1 & 2 off the board the second the season ended, which i'm guessing they were looking at Lance or Jones and they were thinking if they stayed at #12 they might miss out on both.
Remember they did the trade 2 months before the draft so i'd imagine there was hundreds of discussions of who to take. The contingent that wanted Lance won out. So maybe they didn't specifically go up to take Jones but I think part of them going up is because they worried if they settled on Jones and didn't go up Pats would jump up ahead of them.
I do think they still overreacted, Lance would have been there at #12. Falcons were taking Pitts, Bengals, Dolphins and Lions weren't QB needy, Broncos & Panthers traded for QBs. Eagles were really the only question but I think they would have still taken Smith over Lance as they passed on Fields & Jones.
