Playing solely at inside linebacker in 2011, the 6-foot-3, 190-pounder flourished at the position. In total, Douglas racked up 148 tackles, 6 sacks, 5 fumble recoveries, 4 forced fumbles and 2 blocked field goals.
Arlington head coach Scott Peach spoke volumes about his talented linebacker.
"Sammy is our playmaker, if you watch the film from last season he plays inside linebacker for us and he's making every play on the field," Coach Peach said. "Most of all in our team highlights we have he's in the middle of almost all of them.
"He's a sideline to sideline player, he's very physical at the point of contact but he's great in space. Anytime you can have a kid that's 6-foot-3 that is great in space at his position, it created a lot of problems for offenses. I know that there are going to be a lot of people across the country at the college level that will be excited about him. Because we're seeing more and more 6-3, 6-4 kids playing the linebacker position in college simply because they can run."
Peach feels Douglas' best football is still ahead of him after playing the position full-time for the first time last year.
"He started as a sophomore, the only thing we did do a little disservice because we had a need at defensive end and linebacker so played both spots as a sophomore and that's difficult," Peach said. "He still did a good job. His development really came on in the spring going into his junior year when we left him alone and let him play that inside linebacker. That's where we'll keep him."
Although Douglas doesn't hold an offer yet, Coach Peach says plenty of schools have inquired about him and he expects that number to rise once spring practice gets rolling.
"The big conferences that we see most of the time, the Big 12 and SEC, both of them have come in looking at him," he said. "At this point he does not have an offer, I think for him it will play out come spring training time when the recruiting coaches from different schools get out and see him during spring practice. I think it will be in no time when he has several offers in front of him.
