Central Arkansas lost 2 games last year - one to a solid KState team in Manhattan (beat Ohio State, lost to OU by 5), and once in the FCS playoffs. They were dominate in most of their games and ended the regular season FCS #3 (dropped to #10 after the playoffs). They haven't had a losing record for nearly a decade, they are 65/96 since 2010. Central Arkansas enters the season ranked #16 in the FCS. They bring a number of running backs that can put up numbers and their defensive backs seem to be above average. They have 11 players on the preseason all conference list (7 more on second team), just landed a FCS top 10 recruiting class, and it looks like their O-line may go 300+ across the board.
However... they only return two starters to that O-Line and they will be defending a brand new QB - not the wizard they had throwing the ball around last year. The QBs now on the roster include a RS Jr., a RS Soph., a pair of RS Frosh, and a true Frosh (Rivals seems to indicate none were highly recruited at an FBS level). I couldn't find a number for returning starters, but it seems after a quick glance at last years roster and this years that the turnover was about average. I'd think losing the QB and most of the line will hurt the offense - at least until they can gel. 2018 will be a somewhat down year for Central Arkansas.
Tulsa should be flat out more athletic across the board. While Central Arkansas is a good FCS team, they shouldn't stand up to the FBS level, particularly since I think replacing the QB and O line will cost them the crispness they need to pull an upset. Tulsa should be improved this year across the board and though the record last year was poor, there were many close games that could easily have shifted the season to acceptable. It seems Tulsa is also the more experienced team and adds in some bonus starters who missed much of last year from injury. Tulsa has the game at home and should be strongly motivated to make a statement.
Unless Tulsa decides this is a "gimme" and isn't ready to come out and win (or QB performance falls utterly flat), the Bears will not be able to withstand the Hurricane. Central Arkansas puts some points on the board, but they just can't hold on and TU goes into the half in control. I don't think the score will be a runaway because I'm not convinced Tulsa has the deep ball and we can play conservative and still win - plus, we are likely to use the opportunity to try some different personnel packages.
Tulsa: 38
Central Arkansas: 24
Bonus prediction: Luke Skipper takes the first snap, but another QB gets significant playing time.
