Not wanting the thread on this great win to die just yet, I'm going to bring up another great "tale of two halves" in the Reilly Center. Too bad we didn't win the one against Dayton on 1/19/2016. We were blown away in the first half score of 45-18. A radical change saw the Bonnies outscore the Flyers 61-40 in H2. Archie Miller said he was glad the clock ran out when it did with Dayton winning 85-79. Jaylen Adams scored 27 and Posley had 31. However, our "glue guy" didn't score and the turnover-prone Gregg contributed as many TO's as he did points: 3. The Bonnies also lost their next game to VCU, but won 10 of their last 11 A10 games. We were starting to get good again, but got edged out of the A10 tourney in OT by our nemesis, Davidson.
