Depending on whose timeline you're reading, it's possible that NFL teams could be allowed to negotiate contracts with undrafted free agents as early as Monday afternoon. We went into the guys we see as the best UDFAs on offense and defense, but I wanted to add a couple more detailed scouting reports. The first is on Louisville quarterback Adam Froman, who showed a lot of the raw tools to succeed at the NFL level despite just two seasons at the major college level. In 2009 and 2010, Froman threw 243 completions in 403 attempts for 2,987 yards, 17 touchdowns, and nine interceptions.

Accuracy: Good accuracy on the move — will make throws on the run, downfield, against his body, into tight coverage. Will occasionally throw balls with too much flutter, allowing defensive backs to swoop in and deflect or intercept. Better-than-average ability to drop it in the bucket downfield over defenders.

Arm strength: Doesn't have a rocket arm but can make all the necessary NFL throws — intermediate stick routes to the sideline, slants and posts over the middle, timing routes of various distances. Can zip the 9-route with the receiver in stride and looks comfortable doing that you sense the film isn't showing fluke plays. Doesn't throw deep on a rope, however, and he will struggle to make throws in tight windows. Deep balls will sail at times.

Setup/release: Has a compact motion, though the ball comes out a bit lower than the traditional/ideal overhead slot. Made the typical one-step-drop throws in a spread, but also completed enough downfield passes under center. Sets his feet fairly consistently, though he could be trained to drive the ball better because he regresses to throwing off his back foot.

Reading defenses: A work in progress here as in many areas. Froman came to Louisville in 2009 after a stint at Santa Rosa (Ca.) Junior College. Played in a pro-style offense for the Cardinals in 2009, then became the starter in 2010 when the team's new spread offense was jump-started by Froman's mobility. So, he has seen a lot of different defenses, but may not yet have the exposure needed to pick them apart. Tends to telegraph his reads, but will occasionally look off the safety and keep the corner in place.

On the move: Surprisingly gangly in the pocket for such a mobile guy — not a natural in-the-pocket mover. Very dangerous runner on designed plays such as read-option runs — he's agile, has a good second gear in space, and can fit in tight gaps to blast through for extra yards. Impressive juke moves for a taller player. Good at extending the play out of pressure with short and intermediate option throws.

Intangibles: Suffered a thigh injury in 2010 that caused him to miss his final five games.* Still learning the functional passing game; ran a Wing-T offense in high school and was not heavily recruited as a result. Has had three different offensive coordinators in his last three years; could see surprising improvement in his mechanics in the right pro environment. Film junkie who scored a 39 on his Wonderlic.* Schematically versatile quarterback who has played pro-style/play action, option, spread, and pistol — sometimes all in the same game. No known character flaws.

Pro Comparison: Tony Pike, Carolina Panthers — Froman is much faster than Pike on the ground, but both players were late bloomers who impressed in shotgun and under center. *Where Froman intrigues is that he's done enough in limited action in enough different systems to have people wondering just how much he could accomplish if allowed to learn and grow in a consistent system that fits his talent. A vertical West Coast Offense would be a good fit in time; Froman runs rollout pass option enough, and can make enough throws, to eventually be that kind of quarterback. Kevin Kolb might be the upside.
