The Steelers shock the NFL with their first pick in this seven-round mock draft

Round 7 - Pick 251 - Max Duggan, QB, TCU

With Mason Rudolph looking for a new home in free agency, the Steelers are looking for a third-string quarterback. TCU's Max Duggan is the type of player you want in that role, as he's a smart player who has the ability to fill in for Kenny Pickett or Mitch Trubisky if needed.

Could Duggan be this year's version of Brock Purdy? An almost forgotten, "system guy", who makes the most of his chances when called upon? It's possible, although the Steelers certainly hope they won't have to turn to him anytime soon.

But Duggan does have good size (6-2, 207) and speed (4.52 in the 40-yard dash), as well as an accurate arm. He completed 63.7 percent of his passes for 3,698 yards and 32 TDs as a senior, leading the Horned Frogs to the National Championship game. For his efforts, the Heisman Trophy finalist was named the Big 12 Offensive Player of the Year and was the recipient of the Davey O'Brien Award and the Johnny Unitas Golden Arm Award.

Other Possibilities: Clayton Tune, QB, Houston; Stetson Bennett, QB, Georgia; Jake Haener, QB, Fresno State; Malik Cunningham, QB, Louisville; Adrian Martinez, QB, Kansas State

Surprise Pick: Carter Warren, OT, Pittsburgh

If the quarterback the Steelers want for their seventh-round pick isn't available, don't be surprised if they draft Pitt Panthers' offensive tackle Carter Warren. Warren could very well be gone by then, as he's predicted to go in the sixth round by NFLDraftBuzz.com.

But if he's there, the Steelers might want to give this guy a chance. He's 6-6, 311 pounds with 35 3/8-inch arms and a huge wingspan of 84 4/8 inches. Warren missed most of last season due to injury, but prior to that, he spent most of his time playing left tackle for the Panthers.
