IMO, there is much risk in giving up (1) first round & (2) second round picks for Wentz. The risk to me is much higher than drafting a QB that has at least played against tougher competition.
Wentz has only 600 something pass attempts against FCS competition and only ONE game of experience against a FBS opponent (Iowa St). Wentz played well in that game (2014) and ND St won. But then again, Iowa St finished the season 2-10 and their defense was ranked 94th out of 120 FBS schools. When compared to Goff, for example, Goff has over 1200 career pass attempts against FBS schools. He has taken hits, many sacks, and came out unfazed. I'm not campaigning here for Goff as much as I am saying that Goff would be less of a risk in a trade up IMO.
On another note, talking about how the QB's are valued, I have a hard time understanding how one would want to trade up for Wentz by giving future picks, but a player like Kevin Hogan from Stanford is thought of as a backup that isn't worth anything more than a 5th round pick. In 2015, the Cardinal, against all of their Pac-12 opponents, Notre Dame, Pac-12 Champ game, and RoseBowl victory over Iowa, averaged over 41 points a game. They have a good defense, but they didn't squeak out wins ; they dominated teams with their offense. He has good size, moves well, has speed and agility when running, makes good decisions, has 3 years experience against top FBS teams. But, because he's not as accurate as some of the other QB's, he's only valued as a late round prospect? Nothing against Wentz, I just don't understand the vast difference in value between many of the QB's.
