Question: Over/Under: 50 receptions for Jason Witten in 2019?If the over-under is set at 50, will Witten catch more-or-less than 50 passes in 2019?Let's not just take a guess, let's do some math and then apply those numbers to circumstances entering the 2019 season.Witten has been prolific in his career, not only in his number of receptions, but also in playing time and number of targets.Only 3 players in NFL history have more career receptions than Cowboys tight end Jason Witten (1,152): Jerry Rice (1,549), Tony Gonzalez (1,325), and Larry Fitzgerald (1,303).Witten's 1,152 receptions have come in 239 career games.
