With Bentley out for the year, the only thing they can use to judge it is his contract. I would guess probably a 6th-round pick for LeCharles, maybe a 5th since it was a huge contract but no performance is going to hurt.
As for Howard, he has 3 sacks, 4 tackles for loss, and 2 forced fumbles (3rd in sacks, but will finish at least 2nd since Jevon Kearse is 2nd, 1st in tackles for loss, and tied-2nd for forced fumbles). I think we will get at least a 5th, probably a 4th for Darren because he's doing well and signed a good contract.
