Each week, TSN.ca Fantasy Editor Scott Cullen and NFL Editors Ben Fisher and Mike Hetherington discuss three hot fantasy football topics.

Who will finish the better fantasy QB this season, Peyton Manning or Andrew Luck?

Cullen: I'm going with Manning, if only because I don't want to get too high on Luck following a rout of Jacksonville. That's how you end up buying high on players in Fantasy -- take them after they beat up on a bad team -- and while Luck does have the advantage of shaky competition in the AFC South, I'm more confident that Manning's level of play this year isn't far off his record-breaking 2013 season. The touchdowns aren't quite there, yet, but he's on pace for more than 40 touchdown passes and that's despite missing Wes Welker at the start of the year and minimal production from Demarius Thomas, who was expected to be his No. 1 receiver. Basically, I'm siding with track record.

Fisher: I picked Manning to remain on top of the fantasy QB rankings a few weeks ago and I still think he will; but it will be close. We all knew Luck was going to break out as a superstar sooner or later and it appears it’s going to happen very soon, if it hasn’t happened already. Manning has only been really good so far in a year we all expected him to be great, but I still think he holds Luck off for at least one more year.

Hetherington: The passing of the torch has arrived; Luck will top Manning this year. Luck is off to a torrid pace and looking at the schedule, the Colts will face few teams who can slow them down. Manning will have another strong season, but games against the Cardinals, Chargers (twice), Chiefs and Bengals will slow his pace. Luck is flourishing with an array of talented targets in a Colts offence that looks unstoppable. Throw in another matchup against each of the Jaguars and Titans this season (not mention games against the Steelers, Redskins, Browns and Cowboys) and Luck's fantasy numbers could be the best of any QB this season. 

Can Steve Smith Sr. keep up his WR1 production all season long?

Cullen: My natural inclination would be to say that no, the 35-year-old Smith Sr., can't possibly keep up his current rate of production, but he doesn't have to stay at the same level to remain a viable WR1. He's been targeted 10.5 times per game through his first four games with the Ravens -- his previous career-high was 9.87 in 2007 -- so he's getting the work necessary to remain very productive. My concern with Smith would be that, even at his best, he's never been a big touchdown producer and, unless last week's two TD game is just the beginning, I'd still be skeptical that even if he does rack up yardage, that his lack of touchdowns could keep him just below the WR1 level.

Fisher: I hope he can, because it makes for great television, but I’m not so sure. Smith Jr. was a solid WR2 as near back as two years ago but now he’s a little older and extra motivation only goes so far. That said, Smith Jr. had a lot of success with Jake Delhomme in Carolina; Joe Flacco isn’t that much better so you never know. Smith Jr. is worth a start, but I don’t think he holds his WR1 value all year, let alone his crazy early season numbers.

Hetherington: To put it simply, yes. Smith looks like a premier wide receiver in the Ravens offence and with Torrey Smith M.I.A., they need him to stay one. At 35, it's hard to believe Smith will be able to keep up the pace he's set through three weeks (on pace for 100 receptions, 1716 yards and 12 TDs) but he will finish with low-end WR1 numbers. The injury to Dennis Pitta and Torrey Smith's ineffectiveness leave Joe Flacco and the Ravens with no choice but to keep feeding Smith Sr. to have success.

Is this an early season slump for LeSean McCoy, or is it time to worry the preseason No. 1 won't even put up RB1 numbers?

Cullen: It's obviously been a rough start for McCoy and I'm somewhat worried that he's losing some of his touches to Darren Sproles, but McCoy still has 20 touches per game through the first four weeks (down from 22.9 per game last season). Even if the first four games have been awful, I can't fathom that a back who gained 2,146 yards from scrimmage last season suddenly can't fit in among the Top 10 running backs. Come back to me in two weeks and maybe I'll be ready to change my mind.

Fisher: McCoy’s putting up RB1 numbers – we can’t unanimously decide Chip Kelly’s offence does in fact work in the NFL only to change our mind one season later – but I don’t think he’ll finish atop the rankings like he did atop the draft rankings. McCoy’s workload is still very high – as is his talent level – so he’ll move into RB1 territory eventually; he just may not give a full return on his high investment this year.

Hetherington: The injury rumours have started, the Eagles have strived for ways to get the ball in backup Darren Sproles' hands and LeSean McCoy looks like the fantasy bust of 2014. His slow start doesn't guarantee McCoy won't reach RB1 numbers though, and I look for him to find his stride against the Rams struggling run defence this week. If he is injured - rumours of a turf toe injury are abuzz - then the season will likely but lost. However, if he's heathy I expect McCoy to finish as a top-5 running back, but fall short of the lofty expectations owners had.
