Saw this on the 49ers Paradise forum, some of the older scouting reports on JTO from before he was drafted. Keep in mind these are from back in 2002 and I'm sure JTO has developed somewhat since then through his time at various teams and NFLE.
Height Weight 40 Grade
6'2 223 4.92 3.46
Three-year starter named a Division II All-American last season. Passing numbers as a senior were 62.8%/3,826/32/16 after leading the nation (Division II) in passing as a junior when his throwing for 64.2%/3,679/38/11.
Intelligent quarterback with excellent leadership intangibles and a feel for his position. Quick setting in the pocket, tough and stands in against the rush in order to get the pass off. Scans the field, looks off the safety and spreads the ball around to all his receivers. Displays good arm strength, zips the outs and passes have velocity. Senses pressure, gets outside the pocket to make a play on the move and gets rid of the ball rather than taking a sack. Patient in the pocket, buys time for his receivers and accurately places his throws. Must improve his footwork in the pocket as he never really sets his feet and has an unorthodox throwing motion. Starts his throwing motion from the ear and short-arms the pass. Forces the ball into coverage on occasion and really cannot drive the pass downfield. Has been accurate and very productive at a small-school but may have only marginal skills to be considered as a starter at the next level. Still, solid developmental prospect good to have on the sidelines. Mid-Sixth round.
And another one:
QB Thomas "J.T." O’Sullivan
(6-2 1/8, 220, 4.87) California-Davis
Notes: Redshirted in 1997. Backed up Kevin Daft in ’98 and completed 2-of-5 passes for 23 yards, no touchdowns and one interception in the one game he played. Took over as the starting quarterback in ’99 and completed 176-280-2,618-21-11. Led Division II in passing efficiency in 2000, when he completed 141-226-2,648-25-7. If you include Division II playoff games in ’01, he completed 62.8 percent of his passes (255-of-406) for 3,826 yards, 32 touchdowns and 16 interceptions and ran 92 times for 371-2. Coaches call him the best quarterback ever to play at California-Davis, although Ken O’Brien was a first-round pick and a number of other Cal-Davis quarterbacks played in the NFL.
Positives: Nice size. Above-average-to-good athletic ability. Makes some nice throws. Can unload quickly. Can buy time with his feet, throw on the run and has been a pretty effective runner on this level. Has been very productive. Will often carry his team.
Negatives: Tries to do too much himself. Has a way of rubbing some of his teammates the wrong way. Is either arrogant or full of confidence in his ability. Gets away with floating a lot of passes on this level and will have to learn that he can’t do that in the NFL. Quirky delivery. Erratic throwing mechanics and inconsistent release point. At times will drop the ball down too low and use a long, circular-type delivery. Is not an accurate long passer and is inconsistent overall. At times, some of his passes seem to die on him. Temperamental. Was ejected from a game in ’01.
Summary: Has raw ability and a chance to develop if he grows up and learns to control his temper and ego.
And here's what Scouts Inc had to say about him after last season:
You would like to have a little more height so that throwing windows would be there without a lot of movement in the pocket. He is a good athlete with good strength and he shows that he has good foot quickness [with] the ability to move in the pocket to buy time until receivers come open. He gets set up in the pocket quickly and he gets the ball out however he has a bit of a windup in his throwing motion and he needs to become more consistent in his delivery of the ball. He has decent arm strength and he gets good velocity on his short to intermediate passes however he tends to think he can get the ball into spaces where he shouldn't. He has decent accuracy with his short to intermediate passes but he needs to develop more patience in the pocket and do a better job with his pre snap reads and his overall decision making . . . he has some very good physical tools to work with and he has a chance to develop into a very solid back up in the league.
