It's not a problem with burning the year, it's this:
You could also extend him early if you didn't burn the year. Unless you think the big breakout year will be his sophomore year. Which could be the case, but no one knows at this point.
Ultimately though, the issue isn't burning the year, it's burning the year without getting the value from that year. Again, it could be this year, it could be the third year (if you don't burn this year), but you definitely need to get value from one of those years.
