Don't take Julius after one good week against a weak defense.
Ward might be a headache all season for you. (whether or not he gets carries in what will essentially be a 3 RB team, I think Graham will become more involved as the season goes on)
If you want to play the matchup game with Ward and Brown, that may work, but the problem is that you'll never be able to predict how many touches Ward will get week to week. The Bucs head coach has said in interviews that whoever is the "hot" back each game will get more touches.
I'de shop around a bit more, and maybe offer somebody a 2 for 1 trade for a better RB (try to package Hassleback and Benson this week, Benson had his only good week of the season and his value is as high as itll be all year) Don't be so down on the Brown either, at worst he'll be a servicable RB2
Hope I helped, and didnt make things more complicated.
Check out this trade if you have time:viewtopic.php?t=446562
