Re: Donald Young
In 1999, Vince Spadea had a breakthrough year and reached a ranking of around #20. The very next year, he did a complete faceplant which included a record 21 consecutive losses. Donald Young's 2011/2012 reminds me of Vince Spadea.
The good news is that although Spadea fell precipitously in the rankings (to somewhere in the 200's), he doggedly persisted and eventually made it all the way back! There's still hope for Donald!
