Here, the Peterborough Telegraph takes a look at how each fared.
There are success stories as well as failures with plenty of injury woes too unfortunately.
Of this list, David Ajiboye, Kabongo Tshimanga, Aaron Powell and Romoney Crichlow have already left the club.

9. Harley Mills (Enfield)
It's worth remembering that Harley Mills did spend a short period out on loan in September and October before even appearing for Posh this season. It was a tough assignment at struggling Enfield Town in the National League South that provided plenty of defending for him to get stuck into. Enfield lost five of the six matches, conceding 16 in the process, but Mills still managed to stand out and is fondly remembered by the London side. 6 matches. Photo: David Lowndes

10. Aaron Powell (Kettering)
The once highly rated young left-back Powell spent the season on loan at Kettering Town in the Southern League Premier Division Central. He featured in their impressive FA Cup run which saw them beat Northampton in Round One and take Doncaster all the way to extra time in Round Two. Kettering led the league for a long way but were ultimately beaten into second by Bedford and lost 4-2 in the Play-Off Final to Telford. Victory would have seen them promoted to the National League North. Powell was voted Fans Player of the Season. Photo: Joe Dent
