I think they should trade down. They have not had much luck with high picks. http://rotoworld.com/content/playernews.aspx?sport=NFL The Denver Post reports the Lions will likely trade the No. 2 overall pick to a team targeting Wisconsin left tackle Joe Thomas. Here's a new one. A few teams that need a left tackle: the Giants, Cardinals, Dolphins, Colts, Panthers, Bucs, and possibly the Texans
Cardinals would probably be in the best position and are the team that makes the most sense as they need a LT badly. Probably cost them a 2nd and a 3rd or a pick next year and a pick this year.
