Yeah, the same thing I said about Wilmer Flores goes for Tejada as well: whether the Mets re-sign Reyes is going to be determined by what they think of Reyes exclusively and almost certainly NOT be affected by potential SSs already in the system. Disagree -- I think one of the main reasons for deciding to let a popular and proven veteran go is thinking you've got a better choice coming along.
He'll improve as a hitter. He'll be around .300, with a bunch of extra base hits. He'll improve as a fielder, though not as much. He'll be the everyday second baseman, and become a fan faovorite in the Mets' all-homegrown infield.
