Pro Bowl Player
As I understand it, the OL potentially has to make some difficult reach blocks, so you want athleticism over heft.
Kollman talks about it in that video I linked:
For the RB, you want speed and shake over power. So the new super-fast RB they drafted could come into the picture, if not this year then next.
The thing is that both Strange and the new RB Pierre Strong are more suited to zone blocking run plays. So I don't know if the Patriots are planning to change their running schemes to suit two new players when their run game has been pretty strong using gap attacking plays.
Here's a summary of the Patriots offense tendencies in 2021:
"Scheme: McDaniels runs a modified Erhardt-Perkins-style offense molded around the talent on the roster. His offense utilizes multiple formations to run the same play concept, features quick throws (often to the slot receivers or tight ends), attempts to get players into space, and the running game uses mostly Gap run-blocking concepts."
