I think it might be a decent idea. If his contract is similar to Span's, it still shouldn't be an issue if they want to move him. Revere's numbers in his first couple of seasons look farily similar to Michael Bourn's. Minor league numbers were pretty projectable for Bourn and so far, Revere's minor league numbers are also translating. Bourn flashed some power (for the first time and in a contract year) and is going to walk more but he'll also strike out 3x more than Revere. Personally, I think Bourn is overrated. A decent .340-.350 OBP and leading the league in steals doesn't automatically make me think he's an all-world free agent, but it seems a bunch of GM's and baseball wonks seem to disagree seeing as he's one of the top free agents this year and was one of the hottest trade targets last year. If there's a chance Revere could get the same value, I'd lock him up. While I'd be OK with the extension gamble, I think the Twins could wait one more year. Since Revere has no power, I don't think his arb years will be too expensive.
