Certainly within the realm of possibility. And you can go home tonight and not snap at the wife. Dollar valuation is all based on player projections, which are highly variable. There is no such thing as a firm value for any major leaguer, except after the season is over. So to get married to any printed value is foolish.
Every figure has some play, and that play is driven by the market.
The dollar value for any player is only partly a factor of his expected performance. The perceived value by the owners in your league. The stage of the draft you are currently in. The position and category demands when the player comes up for bid. If Chavez's name comes up when there are few thirdbasemen left, it can artificially inflate his value.
