If you're projected to lose by double digits, that might prompt you to take a chance with a boom-or-bust player as opposed to a "safer" option. Ultimately, any player can go off and any player can bust, but looking at floors and ceilings can help guide you to the right decision for your team.As always, RotoBaller factored in usage, matchups, and talent into its Week 15 rankings, and its reflected in its Elias Pettersson Jersey Who to Start? tool. Check out an example from each offensive position. Trevor Lawrence (@ Cowboys) vs. Tua Tagovailoa (@ Bills) vs. Geno Smith (vs. 49ers) vs. Aaron Rodgers (vs. Rams)All of these QBs are capable of popping off for 300 yards and three TDs in any contest, but RotoBaller trusts Lawrence the most despite having the toughest statistical matchup. He's ranked one spot higher than Tagovailoa, who's expected to have to contend with the elements in addition to Buffalo's tough defense this week. Smith is one spot behind him against San Francisco's QB-killing D, while Rodgers is a few spots lower despite having the most favorable matchup. Rodgers simply hasn't shown a high-enough floor this year to be trusted over these QBs, but any of this group could wind up leading the way this week. RotoBaller likely a sumes Lawrence will have the highest volume and highest floor, but if you really need to go for big points, Tua is probably your guy.MORE: and receive exclusive acce s to their lineup tools, rankings, and analysis. . D Erik Gudbranson Jersey 'Onta Foreman (vs. Steelers) vs. Cam Akers (@ Packers) vs. JK Dobbins (@ Browns) vs. Jamaal Williams (@ Jets)This one is all about matchups, as Dobbins ranks the highest despite only returning to the lineup last week. Cleveland has been among the five most generous defenses to RBs all year, so even in a timeshare with Gus Edwards, Dobbins has a high floor and ceiling. Williams is just one spot behind, as he always has high TD potential even in tough matchups. Foreman is next, one spot ahead of Akers, who remains a TD-or-bust flex choice thanks to mediocre volume and little work in the receiving game. None of these backs are sure things, but they should all see at least 12 carries and have decent odds at a touchdown.SN's WEEK 15 STANDARD RANKINGS: | | | | | Gabriel Davis (vs. Dolphins) vs. Michael Gallup (@ Jaguars) vs. Allen Lazard (vs. Rams) vs. George Pickens (@ Panthers)Davis has largely been a disappointment lately, but he still gets the nod in this group by one spot over Pickens and three spots over Lazard. Gallup, despite a highly favorable matchup, brings up the rear. Davis is on the best pa sing offense and Henrik Sedin Men Jersey gets a favorable matchup himself, so unle s weather holds him back, he has a very high ceiling. The rest of this group also has 100-yard, one-TD potential, but Pickens is the safest bet for targets. Gallup is always boom-or-bust, and Lazard could see fewer targets than usual with Christian Watson emerging and Romeo Doubs (ankle) returning. Either way, all have high ceilings, so you can't really go wrong with anyone from this group.SN's WEEK 15 PPR RANKINGS: | | | | | Greg Dulcich (vs. Cardinals) vs. Igor Larionov Men Jersey Pat Freiermuth (@ Panthers) vs. Gerald Everett (vs. Titans)This one comes down to matchups vs. targets. Freiermuth is the safest bet for opportunities, but he has a much tougher matchup than the other two. RotoBaller still ranks him the highest, one spot ahead of Dulcich and four spots ahead of Everett. If you're projected to lose big, taking the higher ceilings of Dulcich or Everett vs. the safer floor of Freiermuth makes sense, so picking from this group really depends on your situation.MORE: and receive exclusive acce s to their premium lineup tools, DFS cheat sheets, and Team Sync platform! .Try out any combination of players including players at different positions for your flex spot with the RotoBaller "Who to Draft?" tool above.
