On draft night, Kansas City traded this year’s first and third-round picks plus a 2018 first-rounder to Buffalo for the No. 10 overall selection, which the team used on rocket-armed Texas Tech quarterback Patrick Mahomes. So the Alex Smith era in KC will soon end — we can’t say exactly when, but it’s happening.

To date, Smith’s tenure with the Chiefs has produced 41 regular season wins over four years and three playoff appearances. He’s completed 64.6 percent of his throws, averaging an unspectacular 7.0 yards per attempt. Kansas City’s offense hasn’t ranked higher than No. 20 in total yardage with Smith at the controls, yet he’s earned two Pro Bowl selections. The partnership between Smith and head coach Andy Reid has been reasonably successful in reality, if not in fantasy. Smith has thrown only 76 touchdown passes in his 61 career starts for KC.

Smith deserves a certain amount of credit for competence, but he’s been a remarkably conservative passer — not merely risk-averse, but risk-intolerant. He didn’t lack dynamic weapons last season, yet he averaged just 3.4 air yards per attempt and 3.1 deep throws per game, ranking near the bottom of the league in both categories according to Player Profiler. Smith remained a zero-upside player for fantasy purposes. In any given week, his statistical ceiling and floor are thisclose. He’s never produced multiple 300-yard games in any of his 11 NFL seasons, an incredible record of non-production in this era.

And now he’s simply a seat-filler for Kansas City, holding the starting QB job only until Mahomes is ready.

Mahomes is entirely unlike Smith in terms of on-field tendencies. He’s fearless to the point of recklessness, perhaps too comfortable challenging coverage and eager to improvise, forever looking for explosive plays. He ran a video game shotgun offense at Texas Tech, passing for over 5000 yards in his final season while averaging 8.5 yards per attempt. Can he stick to an Andy Reid script? Let’s hope. Mahomes is an unnaturally gifted passer, a dual-threat quarterback with weapons-grade arm strength. He’s certainly worth a flier in dynasty formats. Based on talent and team context, I’d take him ahead of Trubisky without hesitation.

It’s possible, of course, that we’ll have to wait a full season to see Mahomes directing the KC offense. He’s not a serious rival to Smith at the moment. For now, Smith remains atop the QB depth chart, constraining this team’s offense. He’s the game-managerest of game-managers, limiting this team’s fantasy potential.

Tyreek Hill and Travis Kelce remain fun, despite their QB.

Hill is blindingly fast, a nightmare coverage assignment. He scored six touchdowns as a receiver last year, three as a rusher, two as a punt returner and one returning a kickoff. That’s just insane. His highlights were of the highest quality. Return TDs are obviously not bankable events in fantasy, but let’s not confuse Hill with someone like Devin Hester. Hill was simply a terrific receiver last season, hauling in 61 passes on 83 targets and excelling on contested balls. His volume should jump in the year ahead with Jeremy Maclin out of the mix — think 110 to 120 targets. At his current draft price (ADP 63.6), I’m plenty interested.

Kelce led all NFL tight ends in fantasy scoring last season, establishing new career highs in targets (117), catches (85) and receiving yardage (1125). With Smith at QB, those numbers are very close to Kelce’s upper limits. He saw 18 red-zone targets and seven inside the 10-yard line, but he only broke the plane four times. Again, that’s not really a surprise for a receiver tied to Smith. When a quarterback only manages 15 passing TDs in as many games, no one is going to finish with double-digit spikes. Kelce doesn’t yet belong to Gronk’s tier at tight end, but he’s solidly in the next group. Personally, I prefer to target guys like Kyle Rudolph, Hunter Henry and Jack Doyle in drafts, because A) they’re available 50 to 80 picks later than Kelce and B) they actually catch touchdowns. But it’s easy to understand the fantasy appeal of the Chiefs tight end; he’s likely to catch 75-80 balls and deliver 900-plus yards.
