There's a classic football saying, “you can't make the club from the tub." Well, in fantasy football it's hard to win the strap if your players aren't getting the snaps. This week, I'm jumping all over the place to hit a number of players at various positions. Here are a baker's dozen of players that are being impacted significantly by a shift in their snaps.

Replacing Gronk

The knee injury suffered by tight end Rob Gronkowski comes at a terrible time for fantasy owners that are either starting their playoffs or looking to secure a spot in the imaginary postseason. Given Gronk's injury is the major headline this week, I'll start off by highlighting some of the more viable replacement options at tight end based on their recent snap counts and productivity.

Managers with Antonio Gates on their roster should also pay attention here. The 35-year-old is currently playing with issues in both his knee and hip. Investing in an insurance policy now could payoff should Gates' body falter during the stretch run. With your league's Gronk owner now on the scent for a good substitute, your options will only be more limited later on.

As the Patriots' No. 2 tight end, Scott Chandler is the most obvious Gronk replacement. He played a season-high 83 percent of the offensive snaps in Week 12 against the Denver Broncos. Gronkowski went down in the fourth quarter, so Chandler's jump in playing time was clearly by design coming into the game. In Week 11, Chandler played a then season-high 52 percent of the snaps, but was only thrown at twice. Against the Broncos, Chandler was targeted a team-high 11 times, caught five balls for 58 yards, and scored his third touchdown of the season. The opposing Philadelphia Eagles have been among the better teams when it comes to defending the tight end position, although they haven't faced many big names. Jason Witten had some success in their two meetings while Greg Olsen was limited to three catches for 65 yards back in Week 7. Although, the Panthers were up 21-6 early in the third quarter of that one. Danny Amendola (knee) looks like he will return, but there's also opportunity for Chandler to see plenty of involvement.

Martellus Bennett has resumed to practicing in full, but that doesn't alter the outlook for Zach Miller very much. Even though Bennett never left the field in Weeks 10 and 11, Miller still saw 80 percent or more of the snaps during those games and was targeted a combined 11 times. Last week without Bennett, Miller played 100 percent of snaps. Against the Green Bay Packers on Thanksgiving he only caught two of his seven targets for 10 yards, but scored his fourth touchdown in four games. The Bears will be hosting the San Francisco 49ers, who have done well against tight ends lately. After allowing three touchdowns to the position in their first five games, no tight end since has scored on the Niners. If you are seeking out a narrative, Bears offensive coordinator Adam Gase was offered the head coaching job of the 49ers, but balked at the mandate that he would have been required to take on Jim Tomsula as his defensive coordinator over incumbent Vic Fangio (now with the Bears). Both coaches will clearly have extra motivation to further bury the 49ers.

Speaking of the Niners, Vance McDonald appears to have found the cure of the drops that had plagued him during his brief time in the league: scoring touchdowns. In the three games since Vernon Davis was traded to the Broncos, McDonald has played 82, 83, and 89 percent of the snaps, respectively. He's also been targeted an average of 5.3 times per game. In addition to scoring a touchdown in each of the last two games, McDonald has caught four passes for 65 yards and six catches for 71 yards. The Bears have only allowed two touchdown receptions by tight ends, but the Broncos combination of Owen Daniels (four catches, 69 yards) and Vernon Davis (six catches, 68 yards) were able to do some limited damage in Week 11.

Position Battles

Matt Forte vs. Jeremy Langford

The rapid assent of the rookie Langford has the Bears needing to strike a balance between utilizing their current star in Forte while also riding the hot hand of the player that will likely replace him as the lead back in 2016. From Weeks 9-11 when Forte was sidelined with an MCL sprain in his knee, Langford's snap percentage ranged from 68-79 percent. With Forte returning on Thanksgiving, Chicago played him on 37 of their 67 offensive snaps while Langford was on the field for the other 30 plays. Neither back was utilized much in the pass game or did a lot as a rusher, outside of Langford's goal line touchdown. The 49ers defense has been decent at home, but putrid on the road. While the matchup for Forte and Langford looks good, this committee approach likely puts a firm cap on their ceiling for the rest of the season. Pick your spots wisely.

Giovani Bernard vs. Jeremy Hill

This has been one of the more interesting situations to look at on a weekly basis, so I find myself putting something about Bernard and Hill into this column every week. During a blowout of the St. Louis Rams, the Bengals were able to balance the snaps between their two backs almost perfectly: 28 for Hill, 27 for Bernard. Perhaps more importantly, while rushing for a season-high 86 yards, Hill exceeded 4.4 yards per carry for the first time all year. Last season, Hill exceeded that mark 10 times. He also matched a season-high long of 15 yards. Last year, Hill met or exceeded that mark in five consecutive games to end the regular season. While we have yet to see those kinds of big plays from Hill, this game is hopefully a sign of good things to come for the fantasy playoffs.

Alfred Morris vs. Matt Jones

The snap percentage charts for Morris and Jones have so many peaks and valleys it looks like a print out from a polygraph machine. However, it looks like the Redskins may have finally had enough of Jones' fumbling issues. After seeing just three snaps in Week 11 due to a rib injury, Morris was on the field for more than 60 percent of the snaps. Jones played a tick above 25 percent, the lowest figure for the rookie since Week 4. To further complicate matters, Chris Thompson is the preferred option in the passing game and sees snaps based on game flow. While Morris is far from a safe option, he's worth a roster spot if anyone in your league has pressed the eject button.

Dontrelle Inman vs. Malcom Floyd

Inman played all 76 of the Chargers offensive snaps in Week 12. Meanwhile, Floyd was on the field for 59 snaps as he tries to play through what was thought to be a season-ending shoulder injury. Inman (nine targets, five catches, 65 yards, one touchdown) also significantly outplayed Floyd (four targets, one catch, 12 yards).
