It’s totally cool for wanting to be faster and wanting to be a better WR and guard. Anyone that dogs on you for those goals is foolish.
I’ve never trained in this respect before, so I’m guessing here- you’re young, you don’t have a lot of training experience, and you need speed above all else.
I would make HIIT and sprints the cornerstone of your training. In the off season, 3x/week, head out to the track and sprint. I don’t think the actual form matters, whether you’re doing 100m, 200m, 30sec, 50sec… just get out there and do it as hard as you can. Rest, wait for readiness, and then do it again.
On two or three other days (depending on how good your recovery is), try one of these abbreviated routines.
Power Snatch: 5x5
Back Squat: 5x5
I’m serious. Two lifts, both done at a challenging (though not backbreaking) weight, for the prescribed reps. Don’t shirk on form, and make sure you do static stretching every day, AFTER your workout.
WS4SB and Starting Strength are also great programs. I recommend what I do because you specifically don’t need any upper body work, both of which are elements of WS4SB and Starting Strength. What you need is speed and power- those two exercises, done right, will get you both in abundance.
What do you eat in a day? Diet is also very important to making good gains, athletically or in body composition?
