Before you make any Dolphins vs. Chiefs picks or NFL picks, you need to see what SportsLine senior analyst Larry Hartstein has to say, given his mastery of picks in games involving Miami.

A former lead writer for Covers and The Linemakers, Hartstein combines a vast network of Vegas sources with an analytical approach he honed working for Pro Football Focus. He tied for 52nd place (out of 1,598 entries) in the 2022 Westgate Las Vegas SuperContest, going 53-34-3 ATS. Those selections form the basis of his weekly SportsLine NFL best bets, which are 69-43-2 since the start of last season, including a 14-4 record the last six weeks.

Most importantly, Hartstein has a read on the pulse of the Dolphins. He is 28-17-1 (+904) on his last 46 picks in games involving Miami! Anyone who has followed him is way up.

Hartstein knows Kansas City quarterback Patrick Mahomes has shown the ability to will his team to victory. Mahomes owns elite arm talent and accuracy to every level on the field. The 28-year-old finished the season sixth in passing yards (4,183), eighth in passing touchdowns (27), and seventh in QBR (62.9).

Hartstein also knows Miami receiver Tyreek Hill is a game-breaking playmaker on the outside. Hill moves all across the formation and is the fastest player in the league. The eight-time Pro Bowl selection was tied for second in the league in receptions (119), but was first in receiving yards (1,799) and receiving touchdowns (13).
