Clemson landed a top 15 recruiting class on National Signing Day, but also added major players to its 2015 class with one of the top offensive linemen in the country and a quarterback with eye-popping numbers.

Offensive lineman Mitch Hyatt (6-6, 265) of Suwanee, Ga., announced his commitment to Clemson. He attended Clemson's junior day earlier this month but was well on his way to a Clemson commitment before that. He's been around the school a great deal as his uncle, Dan Benish, played for the Tigers in the 1980s.

"I just want to get it over with so I can focus on having the best season and helping my teammates," Hyatt said last week."

Hyatt's coach, Bob Sphire, said the junior lineman will make an impact at the college level.

"He is old school tough with modern-day athleticism," Sphire said. "Physically, he is very gifted and very athletic for having that kind of size."

Quarterback Tucker Israel (5-11, 195) of Orlando, Fla., also committed to the Tigers last week. Clemson plans have two quarterbacks in the 2015 class.

"What coach (Chad) Morris was telling me was they got back into meetings and they watched all of the videos of recruits that were on the board and they kept going back to me," Israel said. "They thought they really wanted me and they want me to be their guy. I know that I'm going to a place where I'm going to be loved and have a family."

Some of his other offers include Florida, Indiana, Memphis, South Florida, Akron and Cincinnati. Last season, Israel passed for nearly 4,000 yards with 40 touchdowns. He passed for a combined 66 touchdowns in his freshman and sophomore seasons.
