That might indeed be the case. Because, while Houston has far more sacks AND Houston has the
name recognition (three All Pro seasons and the sack leader in 2014), Houston hasn’t made a Pro Bowl (nor an All Pro team) in half a decade. Maybe Houston is a “sack only” type of player at this point…
…but, I honestly don’t know, because I didn’t watch him with the Colts.
The drop off between what the two players can demand on the open market might have more to do with Ingram’s injury history (than a difference in their levels of play).
