I'm having a hard time seeing Blake Bell make the team as a 4th TE... Rudolph is the starter and Morgan is the best blocking TE on the team. Conklin is freshly drafted and should make the final 53. He's probably most like Rudy in that he's a good receiver and adequate blocker. I think the Vikings will only keep 3 TEs again and go for a 6th WR that can play special teams. Zylstra has been impressive according to the coaching staff... he might stick.
Another thing, I think you're pretty overloaded along the DL... it wouldn't surprise me to see Joseph, Richardson, Johnson, and Holmes be the top 4. Whether they keep Parry or not depends on how well they think Jaleel Johnson can do at NT. I could see 5 given that Holmes could always bump outside to DE.
However, that DE list is going to get trimmed down... keeping 6 is unheard of... Odenigbo was on the PS last year... if he doesn't make a jump, I could see him going back there. Weatherly NEEDS to make a jump... he's entering his 3rd year in the league and has basically been invisible. I wouldn't be surprised if he is cut if someone passes him up on the depth chart. I'm actually highest on Bower... long, strong, and smart. He made some plays in preseason and had a sack in limited snaps during the regular season. I wouldn't count him out of making the final 53.
