Definitely not too late. I highly recommend that you read the entirety of the Rowing Class of 2017 recruiting threat on this website - it is the best thread that I’ve found so far on rowing and recruiting. I’m not sure if your son is a heavyweight or a lightweight, but that will make a difference in the erg scores comparisons. Erg scores are hugely important - probably too important - in the recruiting process. He definitely needs to keep focused on his academics, bringing his 2K erg score as low as possible by the end of his junior year, and getting a lot of experience on the water . Hopefully he loves the sport - that will be perhaps the most important factor and his ability to excel at the sport. I also recommend reading the reddit rowing site - there is some great information there too. He’s got great height for the sport. Good luck.
