I hope bigMike keeps him out a month to allow him to become accustomed to nfl speed, get in practice hits, cuts, turns, catches, etc. Worst thing that could come from playing early would be a high ankle sprain, a knee, or some other season ender. We've waited this long, let's get him game ready, or rather physically ready for the nfl.
The other thing, is how his team mates are gonna respond to him. My guess is that they want to see him produce on the practice field also. But my main concern remains that injury that washes out the rest of his season. Give him a month to get ready physically.
