I'd like to see an upgrade (from your list) at eithe TE or WR. And also LB. maybe RB and CB too. I like Doyle but a better impact type #2 TE would make me feel better. Our receivers are young and smallish.
i don't mean #1 quality, but an upgrade at depth. Maybe the practice squad will accomplish this.
But I think I'm most excited about the potential improvement at OL.
How many times do people have to get told that Green will mostly be playing Dime and Nickel linebacker this year? If Geathers can do that role I'm quite sure Green can as well. Between that and special teams Green will get plenty of playing time this year. He'll do everything and probably a little more than what Geathers did last year which wasn't real complicated. I'm confident he'll be fine in that role.
I could see if they were throwing him to the wolves as the starting Safety next to Geathers and saying "Good Luck Buddy!" They are giving him a role he can perform well with to get experience while learning behind Adams and Geathers until next season. Plus he'll get plenty of work on special teams as well. However I do think an injury here or there is likely to happen this year so he may get thrown in the fire quicker than planned.
Definitely, my grandfather lived in Baltimore for a while and grew up watching him. He still pulled for Indy but always referred to them as Baltimore. I wasn't allowed to say the name Irsay in my house. The game sure has changed. I wish I could go back in time when players didn't get flagged for breathing on a player and defenses were actually feared by offenses.
