We used to see this all the time in the NFL. Rookies would hold out for insane contracts which ended up handcuffing team’s financials for the first several years of that player’s career. Most of the issues came with top-10 picks, but were just more prevalent with first-round picks in general.
Since the new collective bargaining agreement was implemented most of these problems have subsided, but as we’re currently seeing with a handful of draftees, training camp is still the wall for agreements to be finalized. The vast majority don’t trickle into camp anymore, but here we are with an Indianapolis Colts’ second-round pick still unsigned with just 3 days until he’s expected to report to camp.
