Rosen is a very typical first-round quarterback prospect. That's not meant to be a negative statement. The average QBASE for first-round picks since 1997 is 620; Rosen is at 623. The average first-round quarterback has 2.7 years of starting experience; Rosen has three. Rosen's APYA (adjusted passing yards per attempt) of 8.5 and completion rate of 62.6 percent are a little below average for a first-round quarterback prospect, but not by much. (The averages are 9.0 and 64.0, respectively.)
Rosen played a slightly harder than average schedule, but also gets docked by QBASE because he had a lot of high-rated talent around him at UCLA. OT Kolton Miller and TE Caleb Wilson are likely to be first-round picks (Miller this year, Wilson in 2019). C Scott Quessenberry and WR Jordan Lasley are also likely to be drafted this year.

QBASE is projecting only a quarterback's passing performance, so it doesn't care about Jackson's phenomenal running abilities. But QBASE also clearly thinks that talk of Jackson switching positions is kind of silly. He's just as good a quarterback prospect as any of this year's other young passers not named Baker Mayfield.
Jackson has one stat that lags far behind his others: a completion rate of just 59.1 percent in 2017 and just 57.0 percent for his three-year college career. But his AYPA (8.7) and Louisville's passing S&P+ (11th, right below USC) peg him as a late first-round pick. And unlike other prospects who led top passing offenses last year, Jackson didn't have a lot of great talent around him. Any Louisville receivers and linemen who are drafted (perhaps OT Geron Christian this year and WR Jaylen Smith next year) are likely to be Day 3 picks.

Rudolph isn't quite at the Baker Mayfield level, but his raw stats last season were outstanding.
A 10.7 AYPA far surpasses the rest of these prospects, thanks in large part to 37 touchdowns with only nine interceptions. A completion rate of 65.0 percent is also second among these 2017 prospects.
Rudolph's QBASE is lower for two reasons. First, QBASE is factoring in that scouting consensus has Rudolph as a third-round selection, not a first-rounder. Second, unlike Mayfield, Rudolph is getting penalized for putting up his big stats against an easier Big 12 schedule. Mayfield had five games against pass defenses ranked in the S&P+ top 20, while Rudolph had only two (No. 15 TCU and No. 16 Texas).
Kyle Lauletta, Richmond Spiders

Projecting FCS-level quarterbacks is extremely difficult. For Lauletta's projection, we approximated that the pass defenses of the Colonial Athletic Association are roughly equivalent to the lowest FBS conference, the Sun Belt. That would give the average defense faced by Lauletta a rank of 90.8, the worst of this year's top prospects.
Lauletta's 8.7 AYPA in his senior year is similar to what Carson Wentz (8.7) and Joe Flacco (8.6) had in their final FCS years, but is far behind the 10.0 APYA put up by Jimmy Garoppolo.

Falk is right in the cusp of qualifying for QBASE, depending on where he is selected on draft day. The basic idea of only using QBASE on the top 100 picks is that if you drop to the third day of the draft, scouts have probably done a good job of determining that your great college stats are a sign of a system quarterback rather than a top NFL talent.
But Falk didn't even have great college stats. His 6.8 APYA last year was even lower than Allen's 6.9, thanks to short throws (just 10.1 yards per completion) and 13 interceptions.
