Lol. Let's break this down:
The USA Today article you reference states this about Losman - "J.P. Losman's career interception rate (2.73%) was lowest in Tulane history." That's it. Those are the only words written about him. What a ringing endorsement! They also had him the fourth ranked QB in his class, which is like being the 4th best looking chick in class. Someone's gotta be fourth.
The football heavyweight, www.business.highbeam.com, states Mike Martz likes 10 QB's in the draft, one of them being Losman. It then goes on to state his measurables and that he is ranked fourth. Big effing deal.
Finally, your last article, your ace in the hole that "further confirms Losman wasn't really a reach" states:
Positives:
J.P. Losman has the physical attributes you want in an NFL quarterback. He has good size (6-3, 220) and strength, a very strong arm that can make all the throws including the deep out, and one of the quickest releases in all of college football.
Losman has decent agility, and good speed. He also has above average athletic ability. He can make plays with his feet and can throw on the run. He's a fiery competitor, a tough leader and can take a hit. He doesn't get shaken often.
Negatives:
Losman doesn't set his feet real well, throws off his back foot often causing the ball to sail, and doesn't rotate his hips properly. At Tulane, he played mostly out of the shotgun and will have to adjust to playing under center. He tends to rush his throws at times and will force the pass too often. Sometimes tries to make too much happen by himself. Also needs to work on reading coverages a little better.
Projection:
Tulane's J.P. Losman has everything NFL scouts look for in a quarterback, but he needs to polish his game a little, especially his footwork. He should be selected anywhere from the late-first to second round of the 2004 NFL Draft.
Look at the negatives! That's exactly what I do NOT want from my starting QB! And history has proven he WAS a reach, largely for the reasons your ace-in-the-hole article references. The Bills panicked and it cost us yet again.
