Harris still a work in progress with those great numbers and Ive heard him he and his coaches decided a move to TE wasn't in his best interest based on what they had already.
I think it would same here and a setback to his NFL career to make the position change.
He fancy's himself as the next Mike Evans. Hes a matchup problem with this length and speed and it will be easier to get him lose from the outside rather than getting hit by a linebacker or safety early.

The Rams drafting 3 WR has me concerned about Kupps knee.

As far as Skorenek I could see him being tottaly disregarded by Defence s and breaking open in zones for some first downs or scores.
His path to a roster spot would be based on hustle and a superior command of offence and a knack for finding holes in zones along with excellent rapport with QBs.
