You can always tell when it’s spring football season. It’s when the Region I track meet has come and gone.All nine of our coverage-area teams returned to the practice fields this week. Most started on Monday. Some start today. Grapevine starts May 6. Most spring games are going to run right before Memorial Day weekend. Grapevine and Colleyville Heritage will have theirs after the holiday.You might say a bit of reality returns as well. In 2012, we witnessed two of the better quarterbacks in the country in Carroll’s Kenny Hill and Colleyville Heritage’s Cody Thomas. We’ll probably never see that again in our lifetime.This is the grunt work part of the 2013 season. Each of the nine programs has major issues to address. We’ll take them in alphabetical order. Byron Nelson: The Bobcats missed the playoffs in 2012 because of a tough loss to Azle. But head coach Brian Polk has two pressing needs. First, he must basically replace the entire defense, which lost nine starters from the 7-3 squad. Plus, the program could be searching for its third starting quarterback in as many years. Blake Clinton has graduated and Esteban Ortega is out until July with a shoulder injury. So it’s unknown what the offense will look like in May versus what it could look like in August. Carroll: Ryan Agnew is the starting quarterback, replacing Hill. So that’s not the problem. Finding the right people to protect him is what Hal Wasson and his staff are trying to determine. The Dragons do have an anchor in Division I prospect Evan Brown. But after that, there is going to be a lot of time spent developing the rest. They are hoping they have more answers. Colleyville Heritage: The Panthers are trusting that Kiefer Young can handle the offense in place of Thomas. He does have varsity experience, so he understands the speed of the game. Yet Mike Fuller’s offense suffered a huge blow when difference-making wide receiver Kaelin Deboskie moved back to Arizona. The Panthers also have some questions to answer on the defensive line and in the secondary. Grapevine: Dave Henigan needs to find a replacement for three-year starting quarterback Brett Harbin. Plus, he’d love to find a clone for running back Riley Albus. The Mustangs also must get stronger and deeper on both the offensive and defensive lines. Those two areas really hurt this team in 2012. Justin Northwest: A banner 8-3 season for Bill Patterson’s program in 2012 led to a lot of offseason questions. He must replace his leading passer, rusher and receiver. He also needs to find some more defensive help. Keller: There’s more reason to feel good about the Indians. They have some quality candidates at quarterback and arguably two of the best players in the area in defensive end Sione Teuhema and his younger brother, offensive lineman Tristan. What Carl Stralow and his staff have to do is build depth in the program. Keller Central: Despite making the playoffs in 2012, the problem for Bart Helsley’s team was that too much of the burden was placed on quarterback Jake McClurg. Another year should help with his consistency. But this program needs a running back who can make a difference. Keller Fossil Ridge: Tony Baccarini may have one of the best defenses in the area in defensive back Nick Foster and defensive lineman Anthony Villalobos. Finding a go-to wide receiver for quarterback Jake Gnacinski is on the agenda, as well as finding a standout running back. Keller Timber Creek: On April 1, Kevin Golden’s program suffered a major hit when running back Cedric Dale transferred to Hebron. That changed the dynamics of everything they wanted to do offensively. So the question will be finding a suitable replacement.
