According to the St. Louis Blues twitter account Jacob Doty has signed a 3 year entry level deal with St. Louis Blues. https://twitter.com/StLouisBlues
This pretty much paves the road for Doty sticking in the pro's this year, and could solve the Tigers overage situation. Congratulations to Doty!
The Tigers are now at the league minimum 25 roster players and could keep all the players they currently have, however it is likely that 1-2 defenseman may still eventually get sent down.
Looks like Doty's future is still unknown. He may still end up back here. He could be playing in the echl, but I doubt St Louis would sign him to a contract for him to play in the ECHL.
