Of course, in all three types of leagues(dynasty/keeper/re-draft), imo. Although Hester and Know have tools you can't teach, and much more "big-play" potential than Bennett, I think EB has the best chance to become Jay Cutler's primary target. If you've watched any Bears games this year, it's very hard to come away from the game not being impressed with Bennett's excellent hands and route running ability. He may never get you 1500 and 12TD's, but the potential for a consistent 1,000 and 8TD WR as Jay Cutler's most trusted WR is very real.
Maclin has the higher upside, but with Jackson on the team, I think we should all temper expectations just a bit. I'd take him over Bennett(not in a re-draft) in a dynasty/keeper league, but he has boom or bust written all over, at least for the next couple of years, imo.
