It's certainly not too early, the front office has been thinking about it for quite a while so we should too!
I'm commenting partly based on what I would do and partly what I would think the FO will do. I'm not sure where that line is but I don't think I'm far off of their thinking here.
I'd bring back Taylor on a one year deal, maybe even two as a thank you. They are very set on the rookies having to break down the wall to get in the lineup. Lee will not be handed a spot out of spring training. This gives the Martins, Kierseys, Celistinos etc time to figure them selves out while the Buxton situation plays itself out. Taylor can be a valuable trade chip or bench piece if the kids are alright.
I may be in the minority but I'm leaving Lewis in the infield. I've been vocal about leaving him there this year so as to not throw too much on him at once but he appears to be some sort of savant so it may not matter. Defense at third base is very valuable too and I'm not sure his profile fits in center even 2-3 years from now. He seems to be filling out nicely, as my aunt used to say.
If they move him in the off-season and say hes full time center field, I'm all aboard with that but the downstream effects are not easily dismissed. I think they will still be trying to fix Buxton. The most recent reports actually give me hope in that they have been taking a more conservative approach with treatment so far trying to hold off a more major procedure. Obviously, the best outcome is for Buxton to be a regular but it would be wholly irresponsible to proceed as if that's the most likely option.
There is no flippant way to move Lewis to center field without addressing the Buxton question significantly. Had the issue been that Byron had lost a step and was moving to the corner it would be one thing, what we have is completely different. To move Lewis out of the infield both undersells the importance of his value in the infield and oversells the difficulty in finding functional outfield defense. I'm a proponent of making my best defenders touch the ball more which values infield over up the middle. Up the middle infield over up the middle outfield. In short, 3rd base over center field. That may vary for some but I'm team Lewis/Lee or Lee/Lewis and 2nd and 3rd base for as long as we can.
The center field issue will likely be sorted not by positional needs of the team but by best fits of the most valuable organizational pieces.
1. Buxton. Nuf said.
2. Lewis. Can be a double premium in the infield. Minimal benefit to anyone moving to the outfield.
3. Lee. Can push the issue on Polo and Julien. Also double premium in the infield. Correa, Lee, Lewis and a Hoover vacuum in some order around the infield is sexy as hell. I'd rather try to fill center field on the market than break that up.
4. Correa. How many years does he have at short? Keeping Lewis at 3rd keeps his shortstop option open down the road.
5. Jenkins. If they think he can stick in center a bridge from here to there may be best. We may need to start talking about him before we know it. I think hes a Kyle Tucker, who could have played center but was a gold glove in right.
6. Martin. Looking for a home, not a natural center fielder but may be able to play enough to stick. More likely to move around.
