After a strong professional debut in the Hall of Fame game, Carson Beck is drawing fantasy managers' attention. Could he have value this season?The mistake the fantasy market is making about Beck (QB35 ADP) is tied directly to the mistake it's making about Jacoby Brissett (QB28 ADP). The assumption is that Beck -- a third-round rookie who's turning 25 in November -- is Arizona's future franchise quarterback, while Brissett is merely a bridge quarterback who will step aside midseason once the Cardinals are virtually out of playoff contention.What gets lost in this narrative is that despite missing Marvin Harrison Jr. for five of his starts (and the better part of a sixth start), and despite having a backfield comprised of backups, Brissett played so well last season that the franchise decided it was better to pay Kyler Murray a massive sum simply to go elsewhere. Now the Cardinals have a healthy offensive corps that includes future elite rookie RB Jeremiyah Love and capable 1B/backup Tyler Allgeier.I get that Arizona has a potentially brutal intra-divisional schedule that could doom their chances of reaching even six wins. But last year he had 19.4 fantasy points against the #1 defense (Seahawks) in points yielded per game. He posted 20.6 against the #2 defense (Texans). In four other matchups against top-third defenses, he netted 18.3 per game.If the Cards dump him for Beck midseason, there's no going back. Brissett will be a free agent and will sign elsewhere. Beck will have to show that he's better than the guy they let walk.Unless Brissett unexpectedly flops, managers should bank on him to far outperform his QB28 ADP, while Beck learns from the sidelines.For deeper dives on fantasy outlooks, listen to this podcast episode on Brissett and this podcast episode on Beck.This article originally appeared on Touchdown Wire: How much should Carson Beck be on fantasy managers' radars?
