This was supposed to be more of a position debate than line up debate...but whatever works..lol
There is no need to trade Grichuk because he makes 10M. They are no where near the tax threshold, and still dont have any real money committed past 2021.
Depth is a good thing people. They are one injury away (almost anywhere but C) from Grichuk playing everyday. This isn't a rebuilding team anymore that is looking to get kids at bats just to get them at bats. It's put up or shut up time, and you need viable alternatives waiting in line to create that kind of internal competition environment.
Also, I dont think they will play LGJ in RF, I just think they should with this current roster in order to get Biggio somewhere he can be good defensively. If not I think Biggio plays the UT role when everyone is healthy this year and bounces around before he becomes their long term starting 3B. He wasn't very good at 2B, and I think he will be even worse at 3B with the lack of arm strength. If he isn't going to play 2B, I think he can be an average (or better) LF and I also think LGJ can play a solid RF and use that great arm to his advantage even more in RF.
