Should Rockies go with youth at RP?

After going 9-for-9 in save attempts in the month of April, LaTroy Hawkins has been a lot more unsteady in May. He is 2-0 with two saves in three chances, but his ERA over these last eight games is 6.43, and his batting average against is .364. That's part of why Mark Kiszla of the Denver Post is advocating for a changing of the guard for the Colorado Rockies at closer.
