Speed in the 60's

Just drafted a 60's team and secured Morgan, and HAL gave me Brock in LF.
With so little speed in the 60's, it should be a competitive advantage. Plus, none of the teams in my Division have a Catcher with an arm.
Other than their average defense, am I missing something??
ps. I am playing in Yankee Stadium and have Jackson, Powell(Lefebvre) and Mathews(Aspromonte) for power with (LHP insurance)

I'm in your league, and I like the looks of your team. Good luck!

Thanks!
