TAMPA — Based on the first extensive scrimmage of USF's preseason, the Bulls' breakneck offense remains a work in forward progress, though some dazzle can be found amid the defects.The offense accounted for three touchdown passes — two by senior quarterback Steven Bench — and five turnovers during a searing two-hour dress rehearsal Saturday before several dozen spectators at the Morsani Complex.Coach Willie Taggart said the defense — which got points for interceptions, turnovers on downs, etc. — won the day but no winner has emerged in the quarterback duel. Bench had the play of the day, a 95-yard TD pass to redshirt freshman Tyre McCants down the right sideline, but he also had two interceptions.Sophomore QB Quinton Flowers (one interception), who took the day's first snaps, later directed a unit of mostly second-teamers on a 90-yard drive that couldn't score despite first and goal at the 3-yard line."Again, there are too many turnovers," Taggart said. "We know for us, if we don't turn the ball over, we've got a pretty darn good chance. … We want touchdowns; we want scores. We want guys that can lead us down there, who don't turn the ball over and do it consistently."Employing its crisp no-huddle tempo throughout the scrimmage, the offense committed no delay-of-game infractions and appeared steadiest on the ground, with tailbacks Marlon Mack, D'Ernest Johnson and Darius Tice consistently finding running lanes. The quarterbacks, whistled down if touched with two hands, also found regular success on sprint-option and zone-read plays.But the offense struggled mightily near the goal line, an area in which Taggart said the Bulls haven't installed a lot of packages, and was hamstrung by turnovers.On the day's fifth play, Flowers found tight end Sean Price on a short pass for an apparent first down, but Price fumbled. Bench found roommate A.J. Legree on a play-action pass over the middle for a 25-yard touchdown on his first possession but later was intercepted twice by Hassan Childs, once while trying to throw the ball away."We ran a lot of plays, and we did a lot of good stuff," Bench said. "Obviously, there was some stuff that wasn't so good, but that's something we've got to get corrected, and we will. And that's how a scrimmage goes; when you run 100-plus plays, there's going to be some mistakes." CLERVEAUX OUT: Redshirt freshman receiver Stanley Clerveaux suffered a torn ACL during Thursday evening's practice and is out for the season, Taggart said. Clerveaux was sidelined most of 2014 after shoulder surgery.UF FACILITY: Florida coach Jim McElwain did not want an indoor practice facility for the Gators just because everyone else in the SEC has or will have one.McElwain has a detailed plan for how to maximize the use of the $17 million facility once it opens next weekend."I was able to learn from a master on this, obviously, at one of the stops," McElwain said.McElwain was on Nick Saban's staff in 2009 at Alabama when the school renovated its indoor facility. Saban pushed former Dolphins owner Wayne Huizenga to build the team a practice bubble in 2005.Based on his conversations, McElwain said he plans to use the Gators' facility not only to escape Florida's bad weather but its brutal summer heat."You take the beating off the body from that standpoint, which then makes you fresher as the season works at the end," McElwain said. "Any time you can just take the heat drain off, it just helps you in the long run." USF BASKETBALL: Gonzaga transfer Angel Nunez was added to the roster after signing a financial aid agreement. The forward played the past two seasons with the Bulldogs.Information from Times wires was used in this report. Contact Joey Knight at email@example.com. Follow @TBTimes_Bulls.
