DAYTON -- The preseason No. 1 and No. 2 teams in the Pioneer Football League will square off Saturday at Welcome Stadium when the San Diego Toreros visit the University of Dayton
Flyers.

USD (3-1, 2-0 PFL) was picked to finish first in the PFL in a vote of the league's coaches, just two voting points ahead of the Flyers (4-0, 1-0 PFL).  Game time in Dayton is 1 p.m. ET.

UD is 4-0 for the first time since 2007.  

The Flyers did not have to come from behind for the first time this season in last week's 27-14 win at Stetson in the PFL opener.   Redshirt freshman  QB Alex Jeske came into the game with two TD passes in the first three games of the year, but had three in the Stetson win.

This is the 23rd season of the PFL.  UD's 11 titles to date are the most in PFL history, counting ties.  San Diego and Drake are next with six each.

Dayton finished 8-3 overall and 6-2 in the PFL in 2014.  The Flyers finished tied for second in the Pioneer Football League and had their 37th winning season in the last 38 last year. 

Rick Chamberlin is in his eighth season as UD's head coach and returns 14 starters (seven offense, six defense, one specialist) from 2014.

Dayton is led by senior running back Connor Kacsor, who is UD's career record holder in rushing yardage.  A preseason All-American, Kacsor was the 2014 PFL Offensive Player of the Year after gaining 1,547 yards with 17 TD's. 

GOOD NEWS WORTH REPEATING
The Flyers enter the season with the fourth-best winning percentage (.738, 124-41) in FCS football since 2000 AND have produced the most football Academic All-Americans (22) at any level of competition in the same time frame.  The top five in winning percentage are North Dakota State (.845), Harvard (.799), Montana (.775), Dayton (.738), and San Diego (.698).

STREAKING
UD has not been shut out in a school-record 435 straight games, the best such active string in all of college football. The last team to shut out the Flyers was Marshall, 9-0, on Oct. 16, 1976. That is also the all-time FCS record.

SERIES STUFF
Dayton leads the series 15-7.  Last year on Oct. 25 in San Diego, the Toreros scored four of their six TD's in the final three minutes of each half to grab a come-from-behind 40-29 win.
In the last meeting in Dayton, UD won 45-38 in double overtime on Oct. 19, 2013.
Dayton is 8-4 all-time at home against USD.

SCOUTING THE TOREROS
The PFL defending champion, San Diego brings a nine-game win streak in league games into Saturday's contest.
USD is second in FCS football in time of possession (36:05)
The Toreros return eight of nine starters in the trenches from last year's 9-3 team -- all four on the defensive line and four of five on offense.
The defense is led by junior cornerback Jamal Agnew.  The three-year starter is fourth in FCS football in passes defended this season (2.3) after leading last year (2.1). 
Redshirt freshman quarterback Anthony Lawrence took over the starting role after game one, and is second in the PFL in passing efficiency (143.97).  He has completed 72 of 110 passes (.665) for 746 yards with nine TD's.
His favorite target is tight end Ross Dwelley.  Dwelley has 27 catches (10.7 avg.).  He has triple the number of catches of all but one teammate.

PFL POWER
The Pioneer Football League is in its 23rd season.  The original (and now the only) Division I strictly need-based football league began with charter members Butler, Dayton, Drake, Evansville, San Diego and Valparaiso. 
UD's 97-31 PFL mark is the best in PFL history.

600 CLUB
The Flyers were the 11th NCAA FCS team (and the first west of the Alleghenies) to win 600 games in its football history in 2008.
The 16 members of the club, heading into the 2015 season are: Yale (884), Harvard (848), Penn (830), Princeton (804), Dartmouth (676), Delaware (674), Lehigh (671), North Dakota State (671), Lafayette (669), Dayton (649), Northern Iowa (641), Cornell (633), North Dakota (625), Colgate (625), Holy Cross (613) and Brown (601).
Of the 600 Club members, Dayton has played the fewest seasons (106, nine fewer than Northern Iowa's 115).

THE MAN AT THE TOP
Rick Chamberlin is now in his eighth season in charge of the Flyer football program. His record is 59-23.
He is third all-time in wins at Dayton, behind two members of the College Football Hall of Fame -- Mike Kelly (246 wins) and Harry Baujan (124).
Chamberlin is also in his 41st season as part of the Flyer football program.  A Flyer All-American linebacker in his playing days, he has been a part of 353 of UD's 653 wins - 26 as a player, 268 as an assistant coach, and 59 as a head coach.  He has also been a part of 454 of UD's 1,039 games.
The Springfield, Ohio native is the 23rd head football coach since the program began in 1905. He is the first of the 11 modern era coaches to have lettered for the Flyers, and the second to be a graduate of the University of Dayton (Pete Ankney was the first when he coached in 1963 and 1964).
Chamberlin, 59, had been on the Flyer coaching staff for 29 seasons before being named head coach. First as linebackers coach and then as defensive coordinator, Chamberlin helped mold the Dayton D's reputation for its preparation and execution as a unit. Under Chamberlin's guidance as an assistant and now as a head coach, the Flyers have led the Pioneer Football League in scoring defense in nine of the last 12 seasons.
A four-year letterwinner (1975-78) for the Flyers, Chamberlin was named to the Football Coaches Association Small College All-America team. He was the third Dayton player to be named a First Team All-American, and was the first defensive player.  He was inducted in to the UD Athletic Hall of Fame in 1989.
