I'm hoping Kelce turns out to be a stud, and we simply had the misfortune of an unfortunate injury at the start of his rookie campaign.
That said, I would fully be on board with them going after another TE or receiver, to allow them to run more double TE sets.
It could prove to be a lethal package to operate the offense out of, as we could run Jamal out of it as well as pass in a number of ways & with multiple targets- play-action, screens, x'ing routes, hot reads, etc.
It'd be great to get a guy that could line up at the traditional TE spot, but also has enough speed to be able to split out at times. Much like NO's does with Graham, and part of the reason I think the Saints didn't franchise him was because it was already talked about the fact he would appeal to the league about being designated as a TE based on how he is used by them in the hopes of being designated a WR- which would definitely be a lot more if he was paid the average of the top 5 highest paid WRs in the league.
I do think having a true weapon roaming in the middle of the field is where you'll maximize Alex taking advantage of his talents.
