So I guess for re-draft the answer to these questions will help you decide whom to choose: What do you need, consistency or more upside? Is the scoring system generally made up to reward tackles or sacks?
This is the salient point, redraft or not. Neither one of these linebackers has shown enough stud consistency to be counted on a more than a DL2 for the short or long term. Justin Smith may or may not be in a better place than he is now -- but he is what he is, a very good run stopping DE with questionable pass rush skills. Charles Grant has the ability to be the best all-around end in the league but injuries, conditioning and motivation have been issues. And now he's got a big contract.So...
As J Andersson says, do you want the risk of Grant's double digit sack upside or not. Both are safe bets to approach 50 solos. My feeling would be to chase the upside of a guy who's had top five seasons and has the talent to do so again. But there's no fault in taking the guy who's a relatively safer bet to finish as a very good DL2 (12-20 range).
BTW, Grant, injuries, conditioning and perceived poor play aside has exactly one less solo tackle than Smith.
The key is that the Cincinnati home stat crews like to give out assisted tackles (as do Baltimore and Cleveland) so Smith is going to rack up some assists that Grant will not. If that is relevant in your scoring system, then that's worth accounting for as well.
