From 6’0”/160# to 6’3”/200# is a big growth spurt and weight gain in one year. The earliest the kid could have gotten his driver’s license was a year ago, at the age of 16.
No it is not. I was 4' 9" at age 11 when my grandparents came to visit. It was marked and dated on the wall. I had a size 6C shoe. The following year, I was 6' 3/8" with a size 10EE shoe and weighed 112 lbs.
The driver's license on Martin said 6' 0"/160#. If that was on his 16th birthday and he is 17 now (potentially almost 18), that would be 2 years for 3" of growth vertically and 40 lbs. The summer after my 112 lb measurement, I entered 7th grade at age 13 and 135 lb. Another 20 lbs of muscle added in that year.
Look, I have my doubts on all of it.
