If Olsen or Barny got hurt, would you rather have Brockel come in and play TE? Or would you rather it be Cooley?
If Tolbert got hurt, would you rather Brockel play FB/HB? Or would you rather it be Cooley?
I am sure everyone wants better players all around. Would you rather have a better backup QB if Cam got hurt? A number 1 WR option if Smith is out? But, money doesn't grow on trees and you have to use it wisely. Use it in places where it'd have a greater effect, like defense.
You are assuming 3 people get hurt. If you want to take that view, fine with me. But that's not the way I look at it, especially when it comes to the offensive side. We have weapons all around that would compensate if one of those guys went down.
