Karam has already garnered offers from Missouri, Iowa State and Arizona among others. Meanwhile, Mathews currently holds offers from Kansas, Louisville and Tulsa.
The 6-foot-1, 197-pound Karam will be heading to Fort Worth along with his father and head coach and is already very excited to compete.
"It's just a great opportunity to compete in general. But to get to compete against the best, it's going to be a blast. I'm really looking forward to it," Karam said.
One thing that Karam and Mathews have in common other than their running ability, is their belief in their own arm strength.
"I think my arm strength and accuracy will help me stand out from the other guys," Karam said.
However, the 6-foot-3, 180-pound Mathews might have something to say about that.
"I think my deep ball will set me apart. I can throw it pretty far," Mathews said.
Friday might be quite a display of players showing off the cannons that they have for arms.
Although Mathews plans on showing off more than just his arm and feels he'll have a very good showing at the combine.
"I think I'll do real well. I've got good mechanics. I can throw and I've got good footwork. I can use my legs as well as I can use my arm," Mathews said.
While many of the quarterbacks are already well known names and have picked up their share of offers, one player that will be looking to make a name for himself is San Antonio (Texas) Alamo Heights quarterback Drew Allen.
The 6-foot-5, 205-pound gunslinger grabbed his first offer from New Mexico State, but sees the Elite 11 as a chance to showcase his skills against the best.
"I think it's just a great opportunity for me. These guys are being recruited by a lot of colleges and I feel like I just haven't had the opportunity to get my name out there as well," Allen said.
"I just want to do my best, have some fun and be serious about it. Hopefully I can do better than everyone else."
While Allen feels he has the arm strength the throw the deep ball, that's not what he feels will be focused on at the combine.
"I've been working on my accuracy on the underneath routes like the five and out and the slants. I throw a pretty crisp ball to those routes. I can throw the long ball pretty well, but I think when it comes down to it, those underneath routes are the most important," Allen said.
Also expected to be in attendance on Friday are Kenneth Cluley from Waco Reicher, Kolby Gray from Houston (TX) Cypress Falls, Brant Costilla from Parish Episcopal in Dallas and Andrew Maxwell all the way from Midland, Michigan.
