Common mistakes the board helps you avoid
The first is chasing minimum-priced players purely because the value math looks spectacular. A $4,000 backup with a projection borrowed from a small sample will always look efficient on paper; plausibility exists specifically to strip that illusion away. The second is treating the salary cap as a score to maximise — spending all $50,000 is not a goal, and leaving a few hundred dollars unused is fine if the alternative is a worse player.
The third is ignoring the roster rules until the end. Because the FLEX can hold a running back, receiver or tight end, a lineup can look nearly complete and still be impossible to finish under the cap. Watching used and remaining salary as you fill each slot prevents that dead end. The fourth is forgetting to re-upload after news breaks; a lineup built on last night's pricing can be quietly illegal or simply outdated by kickoff.
