Those are the only guys that are pretty much locks to be drafted. Keele would have also been a lock had he not been injured. I still expect Keele to play in the NFL, but he will probably have to catch on as an undrafted FA. Jensen and CB may get drafted but I doubt it, so they will have to go the undrafted FA route as well.
Harline will run about a 4.6 40 (which is what Jolley ran to get picked in the 2nd round), he is plenty fast--he ran away from DB's all season. Plus, he has probably the best hands of any TE in the draft and will show well at the combine.
Beck should also test well at the combine and teams will be impressed with his release, arm strength, and knowledge of the game. Still, I think he will be a 3-4 round pick unless a team really falls in love with him.
