Re-upping Anthony Castonzo at left tackle and signing Rivers to a one-year deal at just the 14th-highest APY (average per year) salary among quarterbacks creates a very high-upside situation for the Colts at the game's most important position. Last season, Pro Football Focus ranked the Chargers' offensive line at No. 29, which is part of why Rivers threw 20 interceptions against just 23 touchdown passes (his fewest since 2007). PFF graded the Colts as the third-best O-line in football last season. This is very impactful, given the style of offense the Rivers-led Colts are likely to run in 2020. One area where Next Gen Stats add some valuable context here: deep passes -- i.e., throws of 20-plus air yards. Rivers threw for just five touchdowns compared to nine interceptions (most in the NFL) on such passes last season. That's a big uptick in picks for Rivers from 2018, when he threw for seven touchdowns against just four interceptions on deep attempts. With the Colts' O-line and rushing efficiencies, Rivers' completion probabilities at any depth project to increase, especially if Indianapolis adds depth at receiver. Between Rivers' reasonable contract, cap space and draft equity (Indy has two picks early in the second round), the Colts have the flexibility to create exceptional long-term value through strategies like drafting a quarterback for the future or upgrading the receiving corps -- without sacrificing this season's win total.
