I assumed he was being genuine...Loomis has consistently said this is a competive team and that he felt injuries ravaged what could have been. I'd like to think during their interview Kellen at least had a similar view of the team.
Of note. If there was ever a position that's primed for a Rookie or young starter its TE. Mostly because developmental snaps are available. Taysom and Foster are injured and if you lose Juwan that leaves only Dallin Holker taking snaps in TC. but because you have taysom/Foster you're unlikely to sign another veteran in that spot unless it's Juwan.
