Can someone please check my grammar?

Hello,

Writing a newsletter for the athlete of the month. Could someone proofread this and give me feedback? Not the best writer in the world lol

"Bobby Williams played for the PPO Bengals last fall and was a top offensive performer, recording eleven touchdowns. He has mastered his receiver skills by participating in on 7 on 7’s nd working with skill coaches to improve his craft. Bobby is the definition of a gym rat, he trains at BPS six times a week and would come seven times a week if he could. He’s a leader in all speed sessions and puts his full effort in every drill he does. He made improvements across the board by dropping his 10-yard dash time from 1.88 to 1.72, 40-yard dash time from 5.78 to 5.30, shuttles from 4.75 to 4.50 and his vertical jump from 21.8 to 24.5 all in just four months of training with us."
