"Essentially a 6'7 WR with reliable hands. He's high cut and lacks some fluidity but shows the ability to create subtle separation."
Strengths:
Lengthy receiving TE with solid speed and quickness for the position. Tough with reliable hands. Has some quickness and physicality in his routes. Aggressive as a blocker and doesn't slack.
Weaknesses:
High cut and lacking ideal fluidity. Blocking is a work in progress and he generally came off the field in obvious run formations.
Overall:
Kolar is a reliable receiving TE that can get into his route and create some separation at the top with regularity. He's capable of making crowd catches and absorbing punishment.
Essentially a big WR, he's got some speed and quick feet in the open field. That said, he's high cut and isn't a fluid route runner or athlete. He's got experience as an inline blocker but he's generally not making a great impact there, although the effort shows up.
