No way that's an even trade. 2 rbs, for 2 better rbs. Sitting out 3 games doesn't change the fact Lewis is an elite RB.
Taylor and Johnson suck ass. Period. 33% of the year over, that's enough for that to be true.
Lewis is a top 5 RB, Dillon is averaging over 100 yds a game, on pace for 1,600 yds but his TDs have been lacking. This should catch up to his yardage. I project Dillon to be just out of the top 5 RBs.
Taylor is having a bad year, period. Rudi is no Corey Dillon. Why exactly would the person make this trade. Get 2 crappier RBs because lewis is gone 2 games? *lol* Come on. Unless the person is 0-5, there's no way he makes this trade. In my league, Taylor and Rudi aren't even starting on their respective teams.
At the end of the year, these RBs won't be even close to each other. The guy needs to sub in for Lewis, then bring him back. Getting 2 disappointments isn't going to help him make the playoffs.
AND if the person needs to make this trade badly, get a different deal. Don't ever take 2 sucky guys hoping they'll magically turn it around on your team. ESP when you're trading an elite (maybe 2) elite RBs.
