A blocking wide receiver who can catch

I mean sure, but you can't sit Olave and Shaheed on the bench when they are by far the best weapons we have. So, you either need to teach them to block or figure something else out. And maybe long term those guys aren't right for the offense or maybe you can only have one of them on the field. Then you move on from one or both when you have a replacement. But, for now you just have to try to teach them to block.

It's probably going to be a combination of teaching them to be more physical or scheming them open. But, going without at least 1 blocking WR will be a mistake.
Coleman is definitely a fine prospect but he struggled to create separation regardless of who his QB was.

34.5% of his targets where considered "contested". This is defined as "a defensive back within close proximity to defend the pass". 34.5% is by far the highest % out of any of the top receivers in this class.

To put it into perspective here's some of the other top WRs in the class.
MHJ: 16.7%
Troy Franklin: 13.5%
Rome Odunze: 20%
Brian Thomas Jr: 14.9%

Now add in his contested catch % which is only 33.3% and you've got a big body receiver who struggles to create separation and then is sub par when it comes to catching said contested passes.

He's getting a lot of comps to Quentin Johnston. It's not fair, but a big bodied WR who can't get separation isn't a good thing.
