I took a look at the stats of Yeremiah Bell and Eric Smith, from 2006-present, since Smith entered the league in 2006. Here is what I came up with:
Tackles: Eric Smith 290, Yeremiah Bell 515
That was expected based on the reputation. But now look at passing related stats:
Passes Defended: Eric Smith 21, Yeremiah Bell 40
Wait, I thought he couldn’t cover anybody?
Interceptions: Eric Smith 5, Yeremiah Bell 5
Again, I thought Bell couldn’t play pass defense?
My point is that Yeremiah Bell is a clear upgrade to Eric Smith, in both the run defense and pass defense. And even if he wasn’t a good pass defender, I don’t think this would happen you Yeremiah Bell:
Yeremiah Bell is clearly a better tackler than that, and for that reason alone he is an upgrade to Eric Smith.
