During the regular season Tim Twentyman will answer 10 good questions from his Twitter account @ttwentyman in a feature we call "10 Questions with Twentyman."
20man: Yet to be determined, but I'd be surprised if he didn't play in some kind of capacity given that the team just traded for one of the best run-stuffing interior defenders in the game, and they host a Seattle team on Sunday that currently ranks seventh in the NFL in rushing at 127.8 yards per game.
It's not like he has to get into playing shape or anything. He's been playing. He's used to controlling the A gap and the B gap, and can play in obvious short-yardage situations.
Like I said, I'd be a little surprised if he didn't play in some capacity Sunday.
20man: This is a good observation. Harrison is one of the more complementary players in the league upfront because of the attention he draws from double teams. With Da'Shawn Hand and A'Shawn Robinson playing pretty well right now – and the potential of Ziggy Ansah returning soon – this is a great addition in that it's going to open up opportunities for a lot of different guys to have one-on-one chances.
It should also have an impact on the linebackers, and allow players like Jarrad Davis to roam a little more free to make plays.
20man: I can't think of one. Getting the first and third-round picks in 2008 for Roy Williams was significant.
As for the mood, the players on defense are pretty excited about it, obviously. Trades in football aren't as prevalent in-season as they are in the other three major sports. To get a player of Harrison's ability, at a point in the season where this Lions team is playing some pretty good football and still very much in the thick of things in the NFC at 3-3, is a boost.
"When I see him in here, I'll be super excited," veteran safety Glover Quin said. "Obviously, he's a great player, great run stopper, d-lineman. Last year, I think he almost had as many tackles as I had as a d-tackle."
20man: I would never completely rule out any other moves, but if the Lions do anything else, it's probably more of a minor depth-type move than a huge trade for a player of Harrison's caliber and contract. Jamal Agnew's knee injury left them a little short at cornerback, maybe a move can be made in the secondary?
20man: He's definitely coming off a very good performance in Miami. I think he's trending in the right direction, and that was always kind of expected as Matt Patricia works so closely with that unit. It was a new scheme, different fundamentals, techniques and cues. It was going to take a little time.
The one thing about Patricia's defenses over the years is he finds a way to maximize the production from the linebacker position. We're starting to see that now with Davis.
Another thing about Davis that's really been impressive this year is his ability to blitz. He leads all non-defensive linemen with a pressure percentage of near 40 percent when he rushes. That's something we didn't see a whole lot of before this season.
There are still things he obviously needs to work on. Continuing to get better in coverage and diagnosing some plays a little faster to get in the right spot to make a play for example, but he's still young and developing. Hopefully last week was a sign of more to come and not just an aberration.
20man: He's battled some knee injuries, and that's always a tricky thing for a receiver. He played well during the second half two weeks ago against Oakland. He's rested coming off the bye, and wasn't on Seattle's injury report to begin this week.
He had six receptions for 91 yards in his last game, so I'd say he was pretty visible and impactful the last time he was on the field. Keep an eye on the toe injury Darius Slay is dealing with this week too. That's a tough injury for a cornerback. I would expect that if Slay plays, he'll see a lot of Baldwin.
20man: Last week in Miami, Luke Willson played 41 snaps, Levine Toilolo played 21 and Michael Roberts played 19.
One thing you have to keep in mind about the tight end position in this current offense is the role they play on the edge and in the second level in the run game as blockers. Willson is a top 12 run blocker at the position, per Pro Football Focus grades. Toilolo has made some pretty big blocks in the run game as well.
Roberts is probably the best receiver of the bunch, and is proving to be a nice weapon in the red zone. That's where I think he's most effective right now.
With the run game humming along like it is, I wouldn't change anything with the tight end rotation. I think the coaches have a pretty good handle on each player's strengths and weaknesses, and they're playing pretty good offensive football right now.
20man: I'll never say never to just about any player on the roster, but to me, the Harrison trade is a signal from upper management that they think this team can win now, and they aren't afraid to deal for the resources to help them accomplish that.
When healthy, Riddick is a player that can help this team in the passing game. I don't think this is a situation in Detroit right now where they're trying to lose assets that can help them win.
20man: Does someone have Johnson on their fantasy team?
That's hard to predict. I can tell you that Seattle's defense ranks 24th in the NFL against the run, allowing on average 120.7 yards per game. So far this year, Seattle has allowed just one 100-yard rusher in six games. That was the 127 yards they gave up to Dallas' Ezekiel Elliott. They have allowed two backs to record over 50 yards in the same game twice, however.
20man: I'll say Kerryon because in the end he's going to have more touches than Golladay.
It was no secret the Lions wanted to get better running the football this offseason, and that threat, led by Johnson, has made them significantly more dangerous to the opposition.
"They've always been a big-time offense. When you have Matthew (Stafford) back there, you have all the fire power you need," Seattle head coach Pete Carroll said in a conference call this week.
"But whenever you can have balance, it just makes it that much harder. You're constantly working year-in and year-out to seek the balance that it takes to have a run game that can complement your passing game, to keep the rush down and all that kind of stuff. So, it's a big factor and it just makes them more dangerous. You can see them just coming to life so clearly under Matt (Patricia) and it's a nice-looking football team right now."
For that reason, I say Johnson.
