Having one simple draft strategy can be detrimental for your overall fantasy football draft health. 

And the fourth round is a perfect representation of why you need to have multiple strategies and players to target, just in case something goes awry in your draft. 

I've already spelled out my favorite players to add and the ones to discard in rounds 1, 2 and 3, so it's time to take a look at round four in terms of average draft position, where past picks determine who you'll pick in this round. 

There's plenty of variance at this level, so here's picks 37 through 48, according to ADP on FantasyPros, which aggregates several fantasy football websites' draft positions. 

37. Kenyan Drake, RB, Miami Dolphins

38. Alex Collins, RB, Baltimore Ravens

39. Zach Ertz, TE, Philadelphia Eagles

40. Deshaun Watson, QB, Houston Texans

41. JuJu Smith-Schuster, WR, Pittsburgh Steelers

42. Brandin Cooks, WR, Los Angeles Rams

43. Larry Fitzgerald, WR, Arizona Cardinals

44. Jarvis Landry, WR, Cleveland Browns

45. Demaryius Thomas, WR, Denver Broncos

46. Lamar Miller, RB, Houston Texans

47. Allen Robinson, WR, Chicago Bears

48. Tom Brady, QB, New England Patriots

I'm not leaving this round,  until I draft...

Allen Robinson.

He's my No. 1 sleeper in this year's fantasy football draft. It's not often you can pick up a legitimate WR1, capable of putting up top-five fantasy points, in the fourth round of the draft. 

But Robinson is that guy. 

In 2015 and 2016 when he was healthy, he was top-10 in targets on a Jacksonville team that was pathetic throwing the ball. His 2015 was far more productive with 1,400 yards and 14 touchdowns, but it's worth noting that he was a target monster in those two seasons. 

You can't always predict production, but it's not difficult to see how often a player is targeted. And on the Bears this season, Robinson is the clear-cut No. 1 receiver, who will dominate the looks from Mitchell Trubisky. 

He's a player that is getting so much value, it's impossible to pass him up. To me, he's very similar to Keenan Allen last year, who was drafted in a similar position. 

Running back value is solid

The running backs in this realm aren't bad for where they're being drafted. 

Drake, Collins and Miller all have tremendous upside, with a few weaknesses. What you're getting with Collins is a No. 1 running back, who was more than adequate last season for the Ravens. He's behind a solid offensive line and he's more than capable of putting up not only RB2 numbers, but regular RB1 figures. 

The Ravens have been known to create volume for running backs they trust, and there's plenty of signs pointing to a solid trust factor with Collins. 

And I'm not sure I'm on board with Miller's ADP. There's very little competition for anyone else gaining touches with the Texans, and with Watson at full health, that should open up holes for Miller. He's a three-down running back who has had major volume since moving to Houston. His production hasn't always been there, but with better quarterback play, it's more than possible his production numbers will rise. 

With Drake, he's unknown, but showed plenty of talent late in the year for the Dolphins in 2017. He's another player capable of playing three downs, so he's someone you can trust. All three of these running backs provide great value. 

Look at all the targets

This round has plenty of opportunities for sleepers. I love wide receivers who can garner targets. And Thomas, Fitzgerald and Landry do that every year at a high level. 

Landry and Fitzgerald generated double-digit targets per game last season, while Thomas was just behind at 8.8. All three are the top targets for each team, so they're going to get volume. 

And with receivers, that's a main issue on a consistent basis. It's hard to trust players who produce on occasion, but only net about four targets per game. All three of these players will garner multiple looks per game. The only weakness is production level, with Landry not scoring touchdowns, and all three having quarterback questions. 

You can't always count on production, but all three of these wide receivers offer WR1 targets, which creates solid value in round 4. 

I'm still skipping quarterbacks

Watson and Brady are probably going to be really good, but this is still too high of a place to draft them with so many other needs on fantasy football rosters. 

While both are really good, there are still major question marks, like with Brady's age and Watson's health. 

Those risks are too much to consider wasting draft capital at this level.
