Sorenson has played against lesser competition at the FCS level with SUU, but possesses prototypical NFL size at 6'5", 229 pounds, and he has a strong enough arm to compete at the NFL level.
The Chargers had only two QBs on the roster prior to drafting Sorenson (Philip Rivers and Charlie Whitehurst), so there will almost certainly be a place for him on the depth chart.
However, Sorenson's role as a perennial backup will be defined rather quickly once he gets to San Diego. Rivers is still only 31 years old and has plenty of gas left in the tank as the franchise center piece for the Chargers. Similarly, Whitehurst is a guy whom San Diego feels comfortable with as a No. 2 option. He is still developing and could eventually get a look as a starter somewhere in the future.
This means that Sorenson will be brought in as the No. 3 guy as the Chargers hope to develop his skill set. Sorenson was on an FBS roster at one point with BYU, but made all of his starts at SUU, throwing for 9,445 passing yards and 61 touchdowns in his three-year career.
He did not look great against elite competition and has the kind of happy feet that can scare you at the next level.
Here is what Bleacher Report's Sigmund Bloom had to say about Sorenson:
The ball gets downfield in a hurry when it comes out of Sorensen's hand, even though he doesn't appear to exert a lot of energy when he throws. He can get the ball on a line to a receiver running a deep out, and he isn't afraid to throw to receivers in tight coverage downfield and give them a chance to make a play. Sorensen will throw the ball into small windows, and he can make a stick throw when he wants to.
Sorensen moves well enough for a big enough, including in the pocket. He can sense pressure but doesn't get rattled by it. He scans and processes the field quickly and resets his feet as he goes through his progressions.
The really good news here is that Sorenson translates perfectly to the Chargers' offensive scheme. He spent a lot of time in the shotgun during his collegiate career and has the type of quick-twitch motion that translates nicely to a West Coast offense.
The hope here will be that Rivers takes on a leadership and mentor role with Sorenson and really shows him the ins and outs of the Chargers offense. He can learn and develop for the next three to four years and then see where he stands at that point.
If that comparison proves true, then the Chargers have mined an absolute gem in the draft's final round. If not, then all the team lost was a seventh-round pick.
