At 5-10, 190, I don't see him capable of succeeding on the perimeter in the NFL. The Packers for sure don't need another slot receiver.
What does height and a WR playing somewhere on the field have to do with anything? There have been plenty of sub-6'0 WR's that have played on the boundary in the NFL and succeed doing it.
Don't tell Steve Smith he can't for example. He is a hall of famer.
Fact is, if you're good, you're good. If you're not, you're not. There isn't some magical height # people want their boundary WR's being.
To flip this coin, there are also plenty of WR's over the years that were OVER 6'0 playing in the slot.
Laveranues Coles
Devin Hester
Steve Smith (Giants)
Santana Moss
DeSean Jackson
Santonio Holmes
Eddie Royal
Greg Jennings (forget about him?)
Steve Smith (Panthers)
The above are some WR's of recent memory that were all under 6'0 and played on the perimeter/boundary in the NFL. Some of them lined up all over, but all of the above played on the boundary a lot.
There are even more examples of this. Antonio Brown at Pittsburgh. Led the league in receiving. TY Hilton is another and he is a playmaker. John Brown and Jaron Brown at Arizona are two sub-6'0 WR's that play on the boundary too. Those are some fast fools who get deep for Palmer.
Did you know that Odell Beckham is under 6'0 too? lol - In fact, I see a lot of Beckham in Coleman. Watch Coleman's highlight videos. He's sick.
There are even MORE examples of sub-6'0 WR's playing the boundary in the NFL in both current day and in the past.
So its not some taboo act or written rule that you shouldn't have perimeter/boundary WR's that are under 6'0. I think its an extremely antiquated way of thinking honestly. Its also shortsighted.
If you're good, you're good, period.
