Tight ends may be the weakest position group in 2020 NFL Draft

Fourth in a series of our updated post-NFL Combine draft prospect rankings, with comments on players who appear likely to be fits for the Bears.

This is not a good year to be shopping for difference-making tight ends in the NFL Draft.

While each of the last three drafts have featured at least three tight ends in the Top 50 picks and three first-rounders in 2017, one in 2018 and two last year, St. Viator High School's and Notre Dame's Cole Kmet is the only prospect this year with a shot at the back of the first round and could be the only one chosen in the first two rounds.

That probably helps to explain why the Bears went hard and fast at both Jimmy Graham and Demetrius Harris in free agency.

This year's crop lacks speed - only three of the top 20 prospects clocked sub-4.7 40-yard dashes - and yet the majority of the best prospects are more likely to play the "U" spot with very few being promising in-line blockers or "Y" tight ends.

The Bears have a number of developmental options at the "U" spot already but the cupboard is bare at the "Y."

Cole Kmet - Kmet may or may not be available for the Bears at 43 or 50 and he appears to be the only tight end prospect the Bears could risk taking that high. He was productive at Notre Dame last season but is still a developmental prospect. He is a two-sport star who chose football over baseball and while already an accomplished receiver he needs work on his blocking. But he does have the frame to add muscle and bulk, and NFL bloodlines. His father, Frank was a Chicago Bear in the early '90s. He is easily the best "Y" prospect in this crop.

Harrison Bryant - Like Kmet, Bryant is a "Y" bet he actually comes out of school more developed as a blocker than receiver. Bryant has the traits to be a pass-catching threat as well but concerns about level of competition in college and the leap to the NFL exist. Want to is definitely not a concern and if the Bears were to trade down, a middle or late round pick in the third could make sense.

Dalton Keene - Keene may be the most complete "Y" prospect of the bunch right now. His blocking at Va. Tech is impressive but he will have to add bulk, muscle and power to be as effective at the next level. Keene may not last until the fifth round but he should be there n the fourth if the Bears are moving around.

Thaddeus Moss - Shorter than you'd like and certainly not the athlete his dad, Hall of Famer Randy Moss is, but a willing blocker who showed up big in the National Title Game for LSU and could be worth a late-round or priority free agent look. He probably gets drafted because of his bloodlines.

Sean McKeon - Looked like a legitimate NFL prospect at Michigan when he was healthy/100 percent but that wasn't often enough his last two seasons. He stands out here with the Bears needs only because he is one of the few legitimate "Y" prospects in this Draft.
