Football season is truly here. Camps all across the country in high school, college and in the National Football League have begun. The first football game of the year will kick off on Sunday at 8 p.m. when my Steelers play Minnesota in the Hall of Fame Game on NBC.

As for your Clemson Tigers, they will not kick off the 2015 season until Sept. 5 when they host Wofford for a 12:30 p.m. kick in Death Valley. However, training camp begins on Tuesday when Clemson takes the field at 4:20 p.m. inside the Indoor Practice Facility.

There are a lot of things the 12^th-ranked Tigers need to complete before camp wraps up on Aug. 18 so here are the top five question marks heading into fall camp.

1. Can Clemson secure its depth on the offensive line? I know Dabo Swinney, and offensive line coach Robbie Caldwell, are surprisingly relaxed heading into camp, but there are major questions on the offensive line when it comes to starters and in overall depth. The talent is there. No one will question that. True freshmen tackles Mitch Hyatt and Jake Fruhmorgen will upgrade the talent level up front as will redshirt freshmen Taylor Hearn and Justin Falcinelli. The departure of Isaiah Battle hurts, however. Instead of Hyatt easing his way into the lineup while playing behind an All-ACC caliber tackle, now he is thrown into the mix as a starter, while Battle’s absence also means the Tigers head into camp with just three tackles. Granted, Caldwell has done a great job of cross training all of his linemen the last few years, but now he has to establish a depth chart that will now have Clemson relying heavily on two true freshmen in its tackle rotation. Also, how does Battle’s decision impact the rest of the offensive line? Will it affect the overall depth of the line since guys like Eric Mac Lain, Maverick Morris and Hearn will now be counted on to play tackle as well?
2. Who will emerge on the defensive line as backup? We all know Shaq Lawson, Kevin Dodd, D.J. Reader and Carlos Watkins will start on the defensive line, but what we really don’t know is who will back those guys up. The defensive end positions seem to be where the biggest question marks are. Outside of Lawson (6-3, 275) and Dodd (6-5, 275) there seems to be very little size in the backups. Everyone feels like Richard Yeargin (6-4, 225) and Chris Register (6-2, 245) will make great defensive ends one day, but right now it is doubtful they are ready. That means the Tigers could lean on true freshman Albert Huggins (6-3, 280) to help out with bulk on the edge. On the inside, true freshman Christian Wilkins is expected to make a big impact and will more than likely fall right into the rotation. If Wilkins can reach those expectations, then with guys like Roderick Byers and Scott Pagano already in the mix, it can give the Tigers a nice five-man rotation at the tackle positions. Huggins might also help out with tackle when he isn’t playing defensive end.
3. How healthy is Deshaun Watson? Yes, Watson has been cleared to practice, but we still don’t know what is going to happen once he gets out on the field and starts competing, again. How will his mental psyche be? Will he trust his knee? Is there going to be rust. These are all questions that more than likely will be answered in the first week of camp. For the record, I think Watson will be just fine.
4. Will Alex Spence be the guy at kicker? We all know about Ammon Lakip. Hopefully, he will clean his mess up and will be back in camp by Aug. 19, when Swinney says he can rejoin the team. Until then, Alex Spence will assume the starting role and will be expected to be kicking for the Tigers when they host Wofford in the season opener? But will Spence ready? I was told coming out of spring practices that walk-on Christian Groomes had a better overall spring than Spence. Spence also struggled in camp last fall and has been inconsistent with his kicking, while adjusting to kicking off the ground. Could Clemson open the season with a walk-on kicker handling the kicking duties? Well, the last walk-on to do that is now kicking for the Arizona Cardinals. By the way, the Tigers will also have a new snapper, holder and punter this year. There are a lot of question marks on special teams heading into this year’s camp.
5. Who will start opposite Mackensie Alexander at cornerback? The numbers Mackensie Alexander put up last season were unreal, and if someone doesn’t think this kid isn’t an All-American candidate then they have not done their homework. So there are no concerns on one side of the field in Clemson’s secondary, but there is a little bit (not much) on the other side. Cordrea Tankersley will enter training camp as the starter, just like last year, but it is not a sure thing. This could be the most intense position battle in camp outside of the running back position. There is no questioning the level of talent at cornerback, but who will be the starter is the question. Right now, that guy could be someone who is not even listed on the Tigers’ current two-deep roster. True freshman Mark Fields has been getting rave reviews from his strength coaches and his teammates since second-summer session started. He will have a chance to compete for Tankersley’s job along with Ryan Carter and Adrian Baker.
