It is tough to compare stats because we do not know how well they would do if for example, Frank didn't have Maggs hitting behind him.
Average: Maggs .317, Lee .291, Frank .267
OBP: Frank .390, Maggs .380, Lee .331
Walks: Frank 100, Maggs 57, Lee 37
Strike outs: Maggs 73, Lee 91, Frank 115
Steals: Lee 18, Maggs 9, Frank 0
If Frank was in the #5 spot, he would probably draw as many walks because of his excellent eye. If they did try and pitch around him because Kong would be next, they still would have to throw strikes.
I'm not certain about putting Lee in that spot. I would prefer Maggs. A little more speed, less strike outs, about the same OBP, fewer walks (bad) and better average.
