Evaluate trade offer?

I think you should not even think about doing this trade. Felipe Lopez is a solid role player on the nationals but his stats are very weak at 2 home runs and 22 RBI's in '06 while batting only .281. Al Reyes, while off to a great start, is a risky player to get because his stats so far could be a fluke. Manny Ramirez however, is a proven player, and has hit 30+ homers and 100+ RBI's the last 10 years. Despite his slow start this year, he will get back on track. Do not do this trade
