Although I know next to nothing about coaching major league baseball I`m going to speculate about it anyway.
I`m happy with most of the coaching staff. However, Bobby Meacham has to go. How many times were Yankees gunned down at the plate this year? I think they need to fire him. Here`s my absurd speculative solution:
1) Fire Bobby Meacham
2) Move Tony Pena to third base, he`s been around these players for a while now and should know when they can make it home and not.
3) Move Rob Thomson to first base. If he chooses to quit then replace him with Luis Sojo.
4) Hire Willie Randolph as the bench coach.
