Decided to look at the ages of the guys on the roster to gauge how young this team really is they are some interesting numbers.
Average age: 27.3 years
Average age w/o goalkeepers: 26.5 years
Players age 30+: 8 (Howard, Rimando, Beasley, Beckerman, Davis, Jones, Dempsey, Wondolowski)
Players age 25-29: 8 (Guzan, Cameron, Besler, Bedoya, Zusi, Bradley, Johnson, Gonzalez)
Players age 24 and under: 7 (Altidore, Chander, Diskerud, Johannsson, Brooks, Yedlin, Green)
Just interesting to look at. I would say the only critical guys in the 30+ group who are probably in their last world cup are Dempsey and Howard. The rest you can argue are fairly easily replaceable. The 25-29 group has a number of key names who will certainly be around for at least 2018 world cup, in particular Bradley and Besler who are going to be huge cogs in the machine in Brazil. And lastly, the 24 and under has the one huge name of importance in Altidore and then the guys everyone wants to see what the can do for the future in Green, Johannsson, Brooks, etc. So it's a decent balance of the talent. I'm very excited to see how the USMNT performs!
