It's safe to say that Reed and Walker are firm a top the best American players with Jordan right on their heals. Walker did his damage late in 2013 when the wrap around season started then Reed started his surge. Jordan shows consistency and a few wins. Walker throws his game back in high gear with 2 wins and consistency in 2015.
They aren't flashy and don't command a great deal of attention in the non golf world. But these three are the best we have and hard tough to beat when they are on with their workman like games. Today I rank them as follows, Walker, Jordan then Reed.
You can see Jordan learning the pro game in front of our own eyes and to me that is pretty cool to see going on. Even at 21 years old he's putting the pieces together each tournament he plays and seems to enjoy and savor learning the game even more. The more experience he gains the smarter he will play and the pieces will begin to fall even more in place. What a talent he is already at 21.
