High school football???????????

hello, im looking to play football in college in the future and had a few questions. im going to be entering my sophomore year in hs, i play dt/de and right tackle and was wondering if i would be able to play those positions on the next lvl based on my size. i currently stan 6 foot 5 and weigh 230 pounds. is it possible for me to get to around 280-300lbs, and if so how could i get to tht weight fast.
