It seems their are people who say, "no, you don't go after the massive FA's, because winners are built from within."
And then, people who say, "we are not winning so their is no rush to get them up here."
I'm not accusing you of being one who says both these things, but to me I don't see how you ever get them up here if that is the case.
If you need your prospects to come up and produce to turn this thing around, but you don't want to call up your prospects until you are in a pennant race, then how will they ever get called up?
To me he is "ready" now. Does he still have some things to work on? Of course. But, he's going on 25 years old. At some point you just have to get him up here and hope that he can learn the rest at this level.
I would assume that there must be some age that is your "cutoff" (maybe not though)? How old would he have to get before you think he should just go ahead and come up with what he has, rather than wait for him to be perfect?
If that age exists, then perhaps we agree on the premise but just disagree on that age. To me, as far as elite prospects go, he's already an "old dog".
I have answered this and I don't especially want to keep hijacking a Dozier thread, but I'll answer again.
It has nothing to do with age, it has to do with the fact that Meyer has two specific things to work on - developing a passable third pitch and improving fastball command. If he can do that he is an ace. He is not there yet. If he is called up he will have some success and some failures, mlb hitters will learn how to exploit those two shortcomings. If he fails, I fear he will fall back on his stuff moreso than keep on developing the two things he needs to work on. I would personally love to see Meyer pitch for the Twins, sooner the better, it might even get me to a couple more games, but I can accept a patient approach here knowing the payoff might be bigger down the line.
All this to say that despite your attempts to generalize this, my thoughts are unique to Meyer in this case.
