I don't think Babs will be in purgatory. Remember Lavalais and Lake as the #3 and #4 DTs last year, each logged about as much time as Jasper and Coleman got last year (20-35 snaps per game).
Babs is going to play a lot, and I suspect he and Coleman will be the guys on the field on a lot of passing downs.
Stopping the run I think may be an issue. We are small in the middle. The Bucs D always had issues with teams that have good OLs and were dedicated to stuffing the ball down their throats. I think we have the same issues because we are built on speed and have very little size. I think teams like the Jets, Panthers, Patriots, and potentially Saints have the rushing capabilities that could exploit us like the Chiefs did last year. But overall, I expect our run defense is going to be good, but I think there may be a game like a Chiefs game where a team just stuffs it down our throats.
To be honest I hav enever seen a tackle play with as little "technique" as Coleman.
You might be right. Coleman has at times looked lost this preseason, and I don't recall that same reaction last year. I'm hoping it's just an overall lacking effort because it's the preseason, and he'll step things up once the season starts and it "matters."
