Based on the contract value, it's possible the Pats don't wind up getting a comp pick for Blount. I don't think they would, if the comp pick system is based on base contract value, without incentives.
But, they work the heck out of the comp system. They got a 5th round comp pick in 2017 for losing Akiem Hicks, a player they didn't even draft and only had for one season. They are line for comp picks in 2018 for Sheard and Bennett, also players they didn't draft and only had for a short time.
This is the hidden potential value of Ballard's short term contracts for guys like Hunt, Mingo, Aiken, Bostic, Spence, Schwenke... if they have decent seasons and earn contracts from other teams, they factor into the 2019 draft comp formula for the Colts, and might bring back a comp pick. We don't have a lot of drafted players that will be demanding new contracts, and guys like Mewhort and Moncrief are probably in the team's plans (I hope). It's not a huge benefit next offseason, but if Ballard continues to bring in young guys on short deals, and if some of them hit for us, it might help us add draft picks.
