Polanco' contract is an example of why you DO sign early long term contracts. Even if he completely tanks--which hasn't happened yet--the dollar figures don't hamstring a team. And if he blows up, he's dirt cheap...like Longoria (who as noted above was signed right after his MLB debut). It might be too late for Buxton and Sano, but they probably should already be under long term contract. The only thing that might change that opinion is if Twins management believes financial security would remove Sano's incentive to control his weight.
