It's tough to truly judge Loeffler after five games. He inherited his current group of players, and they may or may not suit his style of offense. However, Virginia Tech does have some talent on offense and it is up to Loeffler to put his players in position to get the best out of their ability.
Play-calling is the biggest issue with Loeffler. He called for Thomas to run up the middle too many times. How predictable is that? It is a repeat of 2012. It is smart to run your 6'6", 260-pound quarterback up the middle on occasion, but this happens far too often. Get the running backs involved. Use play action more often.
Another issue I noticed with Loeffler was how he used personnel. On a critical third-down play in the second half, he had freshman Joel Caleb in the backfield on a passing play. Running backs who play on third down must be able to block. Needless to say, Caleb missed the block, and Thomas got hit, ending a promising drive.
It's important to note, Caleb didn't begin playing running back until the beginning of summer as he is a former quarterback and wide receiver. Trey Edmunds or Sam Rogers should have been in the backfield on this occasion.
The passing offense did improve versus Georgia Tech. If Thomas continues to improve, then Loeffler's first season as Tech's offensive coordinator will be a success. He certainly deserves ample time to implement his offense.
