Ryan Howard has some an incredible first few years in his career.
But remember, Ruben Sierra put up some awesome numbers in his first few years, batting over 0.300, 30+ homers, 100+ RBIs.
Then he got a big fat contract once his 1st contract ran out, and he got FAT, as in ballooning 30-60 pounds.
His performance got so bad that Tony LaRussa called him "the village idiot" when both were with Oakland.
So, it'll be interesting to see how Ryan does once he gets his big fat contract.
Barry Zito is another example. He did well for Oakland; Scott Boras connived Giants to give Zito a $126M contract, and Zito has just a couple more wins than you and I combined.
