Doing good, keep at it! I played in the late 90s, also a lineman. I've just started getting back in the weightroom recently, I'm taking my son who is in 5th grade.
Obviously methodology changes over time, but I was looking around on some lifting forums. I'm curious, are you just doing front squats? We exclusively did back squats for leg strength in addition to power cleans, dead lifts, leg extensions, etc. Front squat is generally considered safer because it allows for an easier bailout if you're lifting solo, but a back squat done properly will build more leg/quad muscle and allow you to lift more. Back squat can also help with your core. I'd stress that you want to learn proper form though if you're not familiar, have a seasoned person show you how to keep your back straight (One trick I was taught was to look at the ceiling as you're doing your squats. A lifting belt helps too and is good to have as you add more weight). Positioning the bar on your shoulders can be tricky at first too, teaching my son took some time. It helps that our gym has a pad for the bar, we didn't have that when I lifted in high school.
I wouldn't worry too much about the numbers in general right now. I would definitely focus on building those legs for drive blocking though. Foot quickness and lateral movement will help with pass blocking. I was a bigger guy at 6'2" at your age and I wasn't lifting much more on bench. I was benching around 135 around that time, but I never maxed in high school more than like...250 senior year. Looking back I had bad form, I didn't arch my back, my elbows were out, and my grip was just too wide. Good form and less weight is better than bad form and more weight. At the time I asked my coach how best to improve my bench, he stressed building triceps with dumbells. You can also do tricep dips on parallel bars or bench.
Bench is great and helps with initial punch and/or finish, but you want that leg strength to move guys. I really built leg strength from Sophomore to Junior year. I was squatting 15+ reps of 315, I forget what the most was that I did. I went from weighing 185 pounds Sophomore year to hitting 225 Junior year. I didn't miss the weight room during that time, and I was filling up on meat and potatoes. You're in a great period right now where testosterone is high and you've got metabolism, enjoy it and continue putting it to good use! Just remember that consistency is key! You won't see improvement if you aren't going regularly.
