Geoff Collins is intriguing. Big program experience under some good coaches, and also has good record(but short) record as an HC.
At Temple:
Defensive FEI:
2018 - 25
2017 - 29
Offensive FEI:
2018 - 51
2017 - 97
As you can see, Temple took on the image of their HC, which is a very good defensive team. They got slightly better in year 2.
Offensively, they were not great in 2017 but improved a LOT in 2018 even though they came in at just 51 OFEI. That can be attributed to new staff inheriting players and players having to learn a new system. The 4 tier improvement bodes well that the new system was effective in year 2.
Year 3 would be interesting to play out as by then the coach's recruited players will have taken root, and existing players are more comfortable on both sides of the ball. Still, those are promising results for Collins.
