There has been a consistent cycle for the Clemson football program during the last half-decade or so.
The Tigers have fallen short on the biggest stage of them all (2015), followed by winning a National Championship (2016), followed by a shortcoming (2017), followed by another National Championship (2018), followed by coming up short during this past season (2019).
In the years where we saw Clemson football win a National Championship, we saw lots of Tigers exit the program afterwards and be selected in the NFL Draft. In the years where the Tigers lost in the CFB Playoff, we saw a heavy influx of returning talent.
