Yes true on both players because they are such threats in the passing game, however when in line they are not a tell or a liability..unfortunately Gesicki is both in that regard imo.He infrequently lines up inline and wondered if he is considered a "True TE"
Further, what about Kittle who does primarily lineup inline?
p.s. All things being what they are.... I'd like to see the phins use the 13 personnel grouping more.
