100% disagree, you don't even want a slot WR in that offense. In a perfect world, ML wants a 2 WR set with a TE, HB with a FB/TE type back to match.
This offense feeds off the outside zone run game and play-action first and foremost. The whole slot thing was more of a MM thing and what Rodgers was used to for years. Now, people confuse that ML spent his year with the Rams and he wants that system but I have not seen that in his base TW. We know 100% from Jace that AR reverts back to his old stuff....which to me is another whole layer of cluster but I digress.
There was a point I would agree with you. Then the Packers drafted Amari Rodgers. He is the epitome of what you want in a slot receiver. The comparisons of him, to Cobb, has been constant, since the day he arrived in GB. It seemed obvious, to me, that ML intends to explore using the slot to create mismatches, and Rodgers is the type of guy who can set up in the slot, or out wide.
Now, despite what ML views as the way he really wants to run his offense, he's fully aware of the need to create offense around using a slot receiver at times, to exploit weaknesses. He's not going to eliminate it, and knows full well that it's something that Rodgers relates to very well. Hence, getting Cobb back, to run out of the slot, and as a tutor for Rodgers, may not be the dumbest move. It might prove to be a good one. Then there's the fact that Rodgers praise of Kumerow was for a guy that was really a slot player, despite being slower than you'd like.
In the end, I don't doubt for a moment that part of the reasoning for all of it is Rodgers. He's gotten what he wants. Now he needs to make it work. Cobb may well be coming in, to address what his complaint has been for quite some time. Actually, since the time Cobb left the Packers.
All personal observation. We'll know more as the preseason winds down. It's going to be one of the more interesting preseasons we've ever had. We can expect Love to get more reps than normal, because we just don't know. Rodgers could be traded before the season ends.
