I hate to jump on ya, because I feel like you've given a lot of good advice throughout the forum, however I don't think I would advise any kind of split routine to someone who's new to training and looking to "get big for football".
I can't think of many instances in football (or life for that matter) where you only need strength in one half of your body, so why would you train that way?
I say you definitely START with a full-body routine incorporating overhead and bench presses, front & back squats (LOTS OF SQUATS), deadlifts, and cleans. The majority of your strength comes from your bodies ability to transfer movement from your legs and through your core - your training should incorporate that as much as possible. "Bi's and Tri's" should not be a staple in your routine, however you can throw them onto the end of a workout if you feel it's necessary.
Finally, if you're looking to get big, you'll probably need to eat a lot more than 1800 calories, depending on your current size. You can certainly get stronger on that amount of food, but you wont get much bigger.
