Have you ever done a creatine load? And I don't mean taking the 5 grams pre and post workout. At 180 lbs you could load with 30-35 grams A DAY for 10 days and maintain at 15-20 for another 4-5 weeks. You could actually maintain longer. I just like to come off again because of the strength gains I get from loading. Bet sure to drink A METRIC SHITTON of water if you're doing football drills AND lifting. Eat plenty of carbs too.
As someone who used to be a strength & conditioning coach for pro athletes I think I know what your problem is. You're young, have a super high metabolism and on top of that you're burning thousands of calories a day lifting AND doing football drills. Honestly I'd say you're easily burning over 4,000 cals a day if your offseason football program is anything like mine was. Of course we can't all play football in Texas! But you're way ahead of me. I never got over 155 senior year and didn't know anywhere near as much as you about diet and supps. You're already ahead of the curve.
You say you eat 4,000 a day. But what is your exact macro nutrient breakdown: grams protein, grams carbs, and grams of fat? I don't think it'd be insane to say your carbs need to be at least 600+ grams of low glycemic index carbs. You will be eating and shitting alot. The other thing I'd recommend that your probably aren't doing is eating junk food right before bed to slow your metabolism the fuck down. 2 or 3 big macs a night. And no, I'm not kidding. When you tell me more about your complete diet I can make you a full plan and I'm sure others here will have other good advice to input as well.
Side note: as a former strength&conditioning coach I have to say that speed kills. You should never stop doing your speed and conditioning work. Lifting is more fun, but your speed, conditioning, and agility is what's going to win games. Being a strong OLB or DB can't hurt you, but stronger does not always equal better in football, especially outside the trenches. NEVER forgo your speed/agility/conditioning so you can gain more weight. Are you trying to play at the next level? Have any offers yet?
