Most head-to-head fantasy football leagues came to an end after Week 16 was completed on Monday. While fantasy drafts are very important, fairly often the champion of the league made free agency pickups that panned out in a great way for them.

So here is the all-not on your draft radar fantasy football team. These are players who went undrafted in the majority of leagues but were valuable pieces on fantasy rosters.

One quarterback, two running backs, two wide receivers, and one tight end make the team with honorable mentions listed as well.

Quarterback

Alex Smith, Chiefs

2017 stats (through Week 16): 4,042 passing yards, 26 touchdown passes, 5 interceptions, 355 Rushing Yards, 1 rushing touchdown

While Smith has always been superb at not turning the ball over, he hasn't really been fantasy relevant as he has averaged 3,391.5 passing yards and 19 passing touchdowns during his first four years with Kansas City. In 2017, he is sixth in the NFL in passing yards, tied for seventh in passing touchdowns, and fifth among quarterbacks in rushing yards. He has gone over 300 yards passing five times and thrown multiple touchdown passes in seven outings.

Honorable mentions: Jared Goff, Deshaun Watson

Running backs

Alvin Kamara, Saints

2017 stats (through Week 16): 684 rushing yards, 7 rushing touchdowns, 75 receptions, 742 Receiving Yards, 5 receiving touchdowns

A third-round pick in last April's draft, Kamara wasn't expected to get much work as he was behind Mark Ingram and Adrian Peterson (later traded to the Cardinals) in the running back pecking order.

He has scored at least one touchdown in nine of his 15 games and has caught at least three passes in every game. His 75 receptions are tied for 14th in the league.

Dion Lewis, Patriots

2017 stats (through Week 16): 803 rushing yards, 5 rushing touchdowns, 26 receptions, 174 receiving yards, 2 receiving touchdowns

With the Patriots signing Mike Gillislee and Rex Burkhead while still having James White on the roster, there didn't seem to be much of a role for Lewis on New England. After not getting much work in New England's first four games, he has averaged 68.8 rushing yards over the last 11. He is 17th in the NFL with 803 rushing yards. Lewis had a huge Week 16 for many fantasy owners in their championship game finishing with 126 rushing yards, five receptions for 24 yards, and two total touchdowns.

Honorable mentions: Jerick McKinnon, Alex Collins, Javorius Allen, Chris Thompson, Kenyan Drake

Wide receivers

Robby Anderson, Jets

2017 stats (through Week 16): 62 receptions, 939 receiving yards, 7 receiving touchdowns, 8 rushing yards

Anderson had a stretch of five straight games from Weeks 7-12 in which he caught a touchdown pass (two in Week 12).

He has gone over 100 yards receiving three times and has at least four receptions in nine games (eight times in his last 10 outings). He ranks 16th in the league in receptions and tied for 16th in receiving touchdowns.

Nelson Agholar, Eagles

2017 stats (through Week 16): 59 receptions, 757 receiving yards, 8 receiving touchdowns

A first-round pick in 2015, Agholar totaled just 59 catches for 648 yards and three touchdowns in his first two seasons. Only five players have more than the eight touchdown receptions he has on the season. He has scored in eight of Philadelphia's 15 games and has 26 catches in his last four outings.

Honorable mentions: Devin Funchess, Kenny Stills, JuJu Smith-Schuster

Tight end

Evan Engram, Giants

2017 stats (through Week 16): 64 receptions, 722 receiving yards, 6 receiving touchdowns, 14 rushing yards

Engram has been one of the very few bright spots for the 2-13 Giants. The rookie first-round pick has at least four receptions in 11 games. He is fifth among tight ends in receptions, sixth in receiving yards, and tied for sixth in touchdowns.

Honorable mention: Cameron Brate
