You could almost feel the collective exhale of relief for the Colleyville Heritage football team this past Thursday.As much as 2013 has been a struggle – especially offensively – the Panthers put together a performance against Irving that reminded followers of 2012.A 42-0 drubbing of Irving gave the Panthers (5-2, 3-1 in District 6-5A) control of their playoff fate going into Friday’s 7:30 p.m. game against Irving Nimitz (3-4, 2-2) at Mustang-Panther Stadium. The Panthers would clinch a postseason berth with a win.Frankly, there was nowhere to go but up from the win over Irving MacArthur after the offense collected just 122 total yards.Against the Tigers, quarterback Griffin Pickler threw for a career-high 299 yards and four touchdowns. The five-yard toss to Brett Bofinger to start the scoring in the first quarter and the 33-yard deep ball to Bofinger were two of his best throws of his season. The first ball was well placed in the corner of the end zone, where Bofinger was the only one who could catch it. The 33-yard pass went over the top of the secondary. All Bofinger had to do was get under it. The four touchdown passes doubled his season total to eight.Colleyville Heritage struck for 356 total yards and basically went with more of a base approach, Fuller said. “He’s got as good an arm as anybody,” coach Mike Fuller said of Pickler. “The guy can throw the ball. He had a good week of practice. I’m not surprised he did that. He’s strong and accurate. His body language showed he felt confident. We were glad to get that performance.”Bofinger comfortableNow, that he’s about weeks back from his broken collarbone, it’s really been about the last two weeks where senior wide receiver Brett Bofinger hasn’t worried about re-injuring it. He can play free.Bofinger broke out with nine receptions for 134 yards and three scores. His value to the turbo spread can open things up for the likes of Trey Smith and Jake Newell.“It’s starting to get better, and I’m feeling more and more confident,” Bofinger said. “We just have to keep working because we want to make the playoffs.”NotableWith Jacob Sisk’s 57-yard punt return for a touchdown and safety Ryan Phillippe’s 22-yard interception return for a touchdown – his second in as many weeks – the Panthers have scored five non-offensive touchdowns in the last three games … Running back Demarco Corbin (undisclosed injury) played Thursday but it’s clear he’s not 100 percent. Grapevine (1-6, 1-3) at Euless Trinity (5-2, 4-0)7:30 p.m. Friday, Pennington Field, Bedford The skinny: Following an offensive explosion against Carrollton R.L. Turner (508 yards) and 51 points, the Mustangs now turn their attention toward the District 6-5A juggernaut in Euless Trinity. The Trojans haven’t lost a district game since 2004, are coming off a 55-0 thumping of Hurst L.D. Bell, have won their first four district games by an average of 49-14, and have allowed only seven points in the last two games. Grapevine’s Sam Barry is coming off a huge game, rushing for 166 yards and four touchdowns. The Mustangs are going to have to get some help from the Trojans to keep this close, as they are the decided underdogs in this.
