Well we do have a comp 3rd and 4th.. or shouldSeeing as we only have a 1st and 2nd round pick and then don't pick again until the 5th, I would not be oopposed to trading back into the late 1st or early 2nd in order to get more picks. This is assuming guys like Foster and Cunningham are gone by the time we pick. In that case, it would be smart to trade back a few picks and get a DE which is really deep in this draft. There are some guys I see that are late 1st early second which could help us... I have seen Tim Williams dropping in a few mocks due to off the field issues, and then there is TJ Watt who looks really energetic and athletic enough to cover TE's. Even OJ Howard and Njoki, who might not be defensive players, but we do need a TE. So we have plenty of options, but it all depends on how things play out. I would even be as crazy to say to trade up to get Foster, but we're already slim on draft picks as it is.
If there is a player we really like I wouldn't be shocked to see a trade up. My dream scenario is lb in the first and the center (could play guard or center for us) from Ohio state in the second which is probably just wishful thinking
